      * Use a `BoundedVec` in `ValidationResult`

* List all fields when hashing so we don't miss one

* Define types for  `BoundedVec`s of messages

* Fix test compile errors

* Depend on `bounded-collections` 0.1.4 (fixes allocation issue)

* Fix compilation issue

* Derive `Hash` instead of manual `impl`

* Avoid use of unwrap

      Refactor PVF preparation memory stats (#6693) · fd70d012
      Marcin S. authored 
      * Refactor PVF preparation memory stats

The original purpose of this change was to gate metrics that are unsupported by
some systems behind conditional compilation directives (#[cfg]); see
https://github.com/paritytech/polkadot/pull/6675#discussion_r1099996209.

Then I started doing some random cleanups and simplifications and got a bit
carried away. 🙈 The code should be overall tidier than before.

Changes:
- Don't register unsupported metrics (e.g. `max_rss` on non-Linux systems)
- Introduce `PrepareStats` struct as an abstraction over the `Ok` values of
  `PrepareResult`. It is cleaner, and can be easily modified in the future.
- Other small changes

* Minor fixes to comments

* Fix compile errors

* Try to fix some Linux errors

* Mep

* Fix candidate-validation tests

* Update docstring

* Fix some comments and remove a pointless test

* Code review feedback

* Clarification comment in tests

* Some tests

* Reference counted `CandidateHash` in scraper

* Proper handling for Backed and Included candidates in scraper

Backed candidates which are not included should be kept for a
predetermined window of finalized blocks. E.g. if a candidate is backed
but not included in block 2, and the window size is 2, the same
candidate should be cleaned after block 4 is finalized.

Add reference counting for candidates in scraper. A candidate can be
added on multiple block heights so we have to make sure we don't clean
it prematurely from the scraper.

Add tests.

* Update comments in tests

* Guide update

* Fix cleanup logic for `backed_candidates_by_block_number`

* Fixes "for loop over an `Option`" warnings (#6291)

Was seeing these warnings when running `cargo check --all`:

```
warning: for loop over an `Option`. This is more readably written as an `if let` statement
    --> node/core/approval-voting/src/lib.rs:1147:21
     |
1147 |             for activated in update.activated {
     |                              ^^^^^^^^^^^^^^^^
     |
     = note: `#[warn(for_loops_over_fallibles)]` on by default
help: to check pattern in a loop use `while let`
     |
1147 |             while let Some(activated) = update.activated {
     |             ~~~~~~~~~~~~~~~         ~~~
help: consider using `if let` to clear intent
     |
1147 |             if let Some(activated) = update.activated {
     |             ~~~~~~~~~~~~         ~~~
```

My guess is that `activated` used to be a SmallVec or similar, as is
`deactivated`. It was changed to an `Option`, the `for` still compiled (it's
technically correct, just weird), and the compiler didn't catch it until now.
