Treasury Pallet Instance for the Fellowship in Westend Collectives.

In this update, we present a Treasury Pallet Instance that is under the
control of the Fellowship body, with oversight from the Root and
Treasurer origins. Here's how it is governed:
- the Root origin have the authority to reject or approve spend
proposals, with no amount limit for approvals.
- the Treasurer origin have the authority to reject or approve spend
proposals, with approval limits of up to 10,000,000 DOT.
- Voice of all Fellows ranked at 3 or above can reject or approve spend
proposals, with a maximum approval limit of 10,000 DOT.
- Voice of Fellows ranked at 4 or above can also reject or approve spend
proposals, with a maximum approval limit of 10,000,000 DOT.

Additionally, we introduce the Asset Rate Pallet Instance to establish
conversion rates from asset A to B. This is used to determine if a
proposed spend amount involving a non-native asset is permissible by the
commanding origin. The rates can be set up by the Root, Treasurer
origins, or Voice of all Fellows.

Fixes #206

## Status
- [x] Generic `Task` trait
- [x] `RuntimeTask` aggregated enum, compatible with
`construct_runtime!`
- [x] Casting between `Task` and `RuntimeTask` without needing `dyn` or
`Box`
- [x] Tasks Example pallet
- [x] Runtime tests for Tasks example pallet
- [x] Parsing for task-related macros
- [x] Retrofit parsing to make macros optional
- [x] Expansion for task-related macros
- [x] Adds support for args in tasks
- [x] Retrofit tasks example pallet to use macros instead of manual
syntax
- [x] Weights
- [x] Cleanup
- [x] UI tests
- [x] Docs

## Target Syntax
Adapted from
https://github.com/paritytech/polkadot-sdk/issues/206#issue-1865172283



```rust
// NOTE: this enum is optional and is auto-generated by the other macros if not present
#[pallet::task]
pub enum Task<T: Config> {
    AddNumberIntoTotal {
        i: u32,
    }
}

/// Some running total.
#[pallet::storage]
pub(super) type Total<T: Config<I>, I: 'static = ()> =
StorageValue<_, (u32, u32), ValueQuery>;

/// Numbers to be added into the total.
#[pallet::storage]
pub(super) type Numbers<T: Config<I>, I: 'static = ()> =
StorageMap<_, Twox64Concat, u32, u32, OptionQuery>;

#[pallet::tasks_experimental]
impl<T: Config<I>, I: 'static> Pallet<T, I> {
	/// Add a pair of numbers into the totals and remove them.
	#[pallet::task_list(Numbers::<T, I>::iter_keys())]
	#[pallet::task_condition(|i| Numbers::<T, I>::contains_key(i))]
	#[pallet::task_index(0)]
	pub fn add_number_into_total(i: u32) -> DispatchResult {
		let v = Numbers::<T, I>::take(i).ok_or(Error::<T, I>::NotFound)?;
		Total::<T, I>::mutate(|(total_keys, total_values)| {
			*total_keys += i;
			*total_values += v;
		});
		Ok(())
	}
}
```
