* make types within `generate_solution_type` macro explicit

Closes #8444.

Just changes the parsing logic for that macro; does not change any
emitted code. The associated types associated with the macro now
require explicit, keyword-style declaration.

**Old**:

```rust
sp_npos_elections::generate_solution_type!(
	#[compact]
	pub struct TestCompact::<VoterIndex, TargetIndex, PerU16>(16)
);
```

**New**:

```rust
sp_npos_elections::generate_solution_type!(
	#[compact]
	pub struct TestCompact::<VoterIndex = VoterIndex, CandidateIndex = TargetIndex, Accuracy = PerU16>(16)
);
```

* un-ignore doc-tests

* use new form in bin/node/runtime/

* rename CandidateIndex -> TargetIndex

* add tests demonstrating some potential compile failures

* [pallet-staking] Refund unused weight for `payout_stakers` 

fixes #8428

* Use periods in comments

* cargo run --release --features=runtime-benchmarks --manifest-path=bin/node/cli/Cargo.toml -- benchmark --chain=dev --steps=50 --repeat=20 --pallet=pallet_staking --extrinsic=* --execution=wasm --wasm-execution=compiled --heap-pages=4096 --output=./frame/staking/src/weights.rs --template=./.maintain/frame-weight-template.hbs

* Address Shawn's Feedback

* Assert monotomic weights && improve test note

* Remove stray new line

* debug_assert payout_count <= max

* Only track payouts to nominators; not validators

* Trivial comment update

Co-authored-by: Shawn Tabrizi <[email protected]>

* Migrate pallet-proxy to pallet attribute macro

Part of #7882.

Converts the `Proxy` pallet to the new pallet attribute macro introduced in #6877.

[Upgrade guidelines used](https://substrate.dev/rustdocs/v3.0.0/frame_support/attr.pallet.html#upgrade-guidelines).

## ⚠️ Breaking Change  ⚠️ 

From [checking upgrade guidelines](https://crates.parity.io/frame_support/attr.pallet.html#checking-upgrade-guidelines)

> storages now use PalletInfo for module_prefix instead of the one given to `decl_storage`: use of this pallet in `construct_runtime!` needs careful updating of the name in order to not break storage or to upgrade storage (moreover for instantiable pallet). If pallet is published, make sure to warn about this breaking change.

So users of the `Assets` pallet must be careful about the name they used in `construct_runtime!`. Hence the `runtime-migration` label, which might not be needed depending on the configuration of the `Assets` pallet.

### Notes

There are some changes to the docs in metadata for the constants. The docs in the metadata for constants are now more complete.

* bump pallet-node-authorization

* prepping sc-finality-grandpa-warp-sync for release

* bump Cargo.lock
