Currently, when the pallet is compiled with the `insecure_zero_ed flag`,
benchmarks fail because the minimum balance is set to zero.

The PR aims to resolve this issue by implementing a placeholder value
for the minimum balance when the `insecure_zero_ed` flag is active. it
ensures that benchmarks run successfully regardless of whether this flag
is used or not

As per #3326, removes usage of the `pallet::getter` macro from the
balances pallet. The syntax `StorageItem::<T, I>::get()` should be used
instead.

Also, adds public functions for compatibility.

Adds an additional extrinsic call to the `pallet-balances` to _burn_
tokens.
Depending on the `keep_alive` flag, the call might or might not reap the
account.

Required modification of the _fungible's_ `Mutate` trait, `burn_from`
function to allow the `Preservation` argument.

**TODO**
- [x] run benchmarks & update weights
- [x] make sure prdoc is required & properly formatted

Allow for 0 existential deposit in benchmarks for `pallet_staking`, `pallet_session`, and `pallet_balances` (#4346)

This PR ensures non-zero values are available in benchmarks for
`pallet_staking`, `pallet_session`, and `pallet_balances` where required
for them to run.

This small change makes it possible to run the benchmarks for
`pallet_staking`, `pallet_session`, and `pallet_balances` in a runtime
for which existential deposit is set to 0.

The benchmarks for `pallet_staking` and `pallet_session` will still fail
in runtimes that use `U128CurrencyToVote`, but that is easy to work
around by creating a new `CurrencyToVote` implementation for
benchmarking.

The changes are implemented by checking if existential deposit equals 0
and using 1 if so.

good enough for now.

* impl_benchmark_test_suite for ImOnline

For this crate also, the test suite fails identically with and without
this change, so we can say that this change is not the cause of the
tests' failure to compile.

* impl_benchmark_test_suite for lottery

* impl_benchmark_test_suite for merkle-mountain-range

* impl_benchmark_test_suite for Multisig

* impl_benchmark_test_suite for Proxy

Fails identically with and without this change.

* impl_benchmark_test_suite for scheduler

* impl_benchmark_test_suite for session

It turns out to be important to be able to exclude items marked

* fix wrong module name in impl_benchmark_test_suite in Offences

* address line length nits

* enable optional keyword argument: exec_name

Took a _lot_ of macro-wrangling to get the functionality that I want,
but now you have the option to pass in

```rust
impl_benchmark_test_suite!(
	Elections,
	crate::tests::ExtBuilder::default().desired_members(13).desired_runners_up(7),
	crate::tests::Test,
	exec_name = build_and_execute,
);
```

and have it expand out properly. A selected fragment of the expansion:

```rust
        fn test_benchmarks() {
            crate::tests::ExtBuilder::default()
                .desired_members(13)
                .desired_runners_up(7)
                .build_and_execute(|| {

This prs cleans up some of the frame benchmarking stuff:
- Move CLI into `frame-benchmarking-cli`. No frame related CLI should
exists in the default Substrate CLI.
- Move all traits and types related to frame benchmarking into the
`frame-benchmarking` trait. Frame types should be isolated in Frame.

* De-duplicate

* Refactor away the UpdateBalanceOutcome

* Expunge final UpdateBalanceOutcome refs
