      [frame] `#[pallet::composite_enum]` improved variant count handling + removed `pallet_balances`'s `MaxHolds` config (#2657)
      
      I started this investigation/issue based on @liamaharon
      
       question
      [here](https://github.com/paritytech/polkadot-sdk/pull/1801#discussion_r1410452499).
      
      ## Problem
      
      The `pallet_balances` integrity test should correctly detect that the
      runtime has correct distinct `HoldReasons` variant count. I assume the
      same situation exists for RuntimeFreezeReason.
      
      It is not a critical problem, if we set `MaxHolds` with a sufficiently
      large value, everything should be ok. However, in this case, the
      integrity_test check becomes less useful.
      
      **Situation for "any" runtime:**
      - `HoldReason` enums from different pallets:
      ```rust
              /// from pallet_nis
              #[pallet::composite_enum]
      	pub enum HoldReason {
      		NftReceipt,
      	}
      
              /// from pallet_preimage
              #[pallet::composite_enum]
      	pub enum HoldReason {
      		Preimage,
      	}
      
              // from pallet_state-trie-migration
              #[pallet::composite_enum]
      	pub enum HoldReason {
      		SlashForContinueMigrate,
      		SlashForMigrateCustomTop,
      		SlashForMigrateCustomChild,
      	}
      ```
      
      - generated `RuntimeHoldReason` enum looks like:
      ```rust
      pub enum RuntimeHoldReason {
      
          #[codec(index = 32u8)]
          Preimage(pallet_preimage::HoldReason),
      
          #[codec(index = 38u8)]
          Nis(pallet_nis::HoldReason),
      
          #[codec(index = 42u8)]
          StateTrieMigration(pallet_state_trie_migration::HoldReason),
      }
      ```
      
      - composite enum `RuntimeHoldReason` variant count is detected as `3`
      - we set `type MaxHolds = ConstU32<3>`
      - `pallet_balances::integrity_test` is ok with `3`(at least 3)
      
      However, the real problem can occur in a live runtime where some
      functionality might stop working. This is due to a total of 5 distinct
      hold reasons (for pallets with multi-instance support, it is even more),
      and not all of them can be used because of an incorrect `MaxHolds`,
      which is deemed acceptable according to the `integrity_test`:
        ```
        // pseudo-code - if we try to call all of these:
      
      T::Currency::hold(&pallet_nis::HoldReason::NftReceipt.into(),
      &nft_owner, deposit)?;
      T::Currency::hold(&pallet_preimage::HoldReason::Preimage.into(),
      &nft_owner, deposit)?;
      
      T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForContinueMigrate.into(),
      &nft_owner, deposit)?;
      
        // With `type MaxHolds = ConstU32<3>` these two will fail
      
      T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForMigrateCustomTop.into(),
      &nft_owner, deposit)?;
      
      T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForMigrateCustomChild.into(),
      &nft_owner, deposit)?;
        ```  
      
      
      ## Solutions
      
      A macro `#[pallet::*]` expansion is extended of `VariantCount`
      implementation for the `#[pallet::composite_enum]` enum type. This
      expansion generates the `VariantCount` implementation for pallets'
      `HoldReason`, `FreezeReason`, `LockId`, and `SlashReason`. Enum variants
      must be plain enum values without fields to ensure a deterministic
      count.
      
      The composite runtime enum, `RuntimeHoldReason` and
      `RuntimeFreezeReason`, now sets `VariantCount::VARIANT_COUNT` as the sum
      of pallets' enum `VariantCount::VARIANT_COUNT`:
      ```rust
      #[frame_support::pallet(dev_mode)]
      mod module_single_instance {
      
      	#[pallet::composite_enum]
      	pub enum HoldReason {
      		ModuleSingleInstanceReason1,
      		ModuleSingleInstanceReason2,
      	}
      ...
      }
      
      #[frame_support::pallet(dev_mode)]
      mod module_multi_instance {
      
      	#[pallet::composite_enum]
      	pub enum HoldReason<I: 'static = ()> {
      		ModuleMultiInstanceReason1,
      		ModuleMultiInstanceReason2,
      		ModuleMultiInstanceReason3,
      	}
      ...
      }
      
      
      impl self::sp_api_hidden_includes_construct_runtime::hidden_include::traits::VariantCount
          for RuntimeHoldReason
      {
          const VARIANT_COUNT: u32 = 0
              + module_single_instance::HoldReason::VARIANT_COUNT
              + module_multi_instance::HoldReason::<module_multi_instance::Instance1>::VARIANT_COUNT
              + module_multi_instance::HoldReason::<module_multi_instance::Instance2>::VARIANT_COUNT
              + module_multi_instance::HoldReason::<module_multi_instance::Instance3>::VARIANT_COUNT;
      }
      ```
      
      In addition, `MaxHolds` is removed (as suggested
      [here](https://github.com/paritytech/polkadot-sdk/pull/2657#discussion_r1443324573))
      from `pallet_balances`, and its `Holds` are now bounded to
      `RuntimeHoldReason::VARIANT_COUNT`. Therefore, there is no need to let
      the runtime specify `MaxHolds`.
      
      
      ## For reviewers
      
      Relevant changes can be found here:
      - `substrate/frame/support/procedural/src/lib.rs` 
      -  `substrate/frame/support/procedural/src/pallet/parse/composite.rs`
      -  `substrate/frame/support/procedural/src/pallet/expand/composite.rs`
      -
      `substrate/frame/support/procedural/src/construct_runtime/expand/composite_helper.rs`
      -
      `substrate/frame/support/procedural/src/construct_runtime/expand/hold_reason.rs`
      -
      `substrate/frame/support/procedural/src/construct_runtime/expand/freeze_reason.rs`
      - `substrate/frame/support/src/traits/misc.rs`
      
      And the rest of the files is just about removed `MaxHolds` from
      `pallet_balances`
      
      ## Next steps
      
      Do the same for `MaxFreezes`

      Add limits to XCMv4 (#3114) · cc4805b5
      Francisco Aguirre authored
      
      Some more work regarding XCMv4. Two limits from v3 were not transferred
      over, those are:
      - The instructions limit
      - The number of assets limit
      Both of these are now in v4.
      
      For some reason `AssetInstance` increased in size, don't know why CI
      didn't catch that before.

      [cumulus] `parachains-common` testnet constants cleaning (#3134) · 4450b615
      Branislav Kontur authored
      
      The `parachains-common` contains a lots of constants and type
      definitions which are used for `polkadot-sdk`'s testnet runtimes and
      also for `polkadot-fellows`'s production [SP
      runtimes](https://github.com/polkadot-fellows/runtimes/tree/main/system-parachains/constants).
      This PR cleans `parachains-common` module to contain only common and
      generic functionality.
      
      Testnet-specific constants have been moved to the separate module
      dedicated just for testnets:
      `polkadot-sdk/cumulus/parachains/runtimes/constants/`

      Continues the work of https://github.com/paritytech/polkadot/pull/7312.
      `MultiLocation` was modified to implement serialize in no-std in that
      PR, but not the assets types.
      This PR does the same for assets, and this also allows to inject them in
      pallets that require them in genesis.

      Removes the `Default` implementation for `RewardDestination` (#2402) · a9992dbb
      Gonçalo Pestana authored
      
      This PR removes current default for `RewardDestination`, which may cause
      confusion since a ledger should not have a default reward destination:
      either it has a reward destination, or something is wrong. It also
      changes the `Payee`'s reward destination in storage from `ValueQuery` to
      `OptionQuery`.
      
      In addition, it adds a `try_state` check to make sure each bonded ledger
      have a valid reward destination.
