Change `redundant_pattern_matching` to also lint `std::task::Poll`
`reduntant_pattern_matching` currently lints pattern matching on `Option` and `Result` where the `is_variant` utility methods could be used instead: `is_some`, `is_none`, `is_ok`, `is_err`. This PR extends this behaviour to `std::task::Poll`, suggesting the methods `is_pending` and `is_ready`.
Motivation: The current description of `redundant_pattern_matching` mentions
> It's more concise and clear to just use the proper utility function
which in my mind applies to `Poll` as well.
changelog: Enhance [`redundant_pattern_matching`] to also lint on `std::task::Poll`
Qualify `panic!` as `core::panic!` in non-built-in `core` macros
Fixes#78333.
-----
Otherwise code like this
#![no_implicit_prelude]
fn main() {
::std::todo!();
::std::unimplemented!();
}
will fail to compile, which is unfortunate and presumably unintended.
This changes many invocations of `panic!` in a `macro_rules!` definition
to invocations of `$crate::panic!`, which makes the invocations hygienic.
Note that this does not make the built-in macro `assert!` hygienic.

Drop support for all cloudabi targets
`cloudabi` is a tier-3 target, and [it is no longer being maintained upstream][no].
This PR drops supports for cloudabi targets. Those targets are:
* aarch64-unknown-cloudabi
* armv7-unknown-cloudabi
* i686-unknown-cloudabi
* x86_64-unknown-cloudabi
Since this drops supports for a target, I'd like somebody to tag `relnotes` label to this PR.
Some other issues:
* The tidy exception for `cloudabi` crate is still remained because
* `parking_lot v0.9.0` and `parking_lot v0.10.2` depends on `cloudabi v0.0.3`.
* `parking_lot v0.11.0` depends on `cloudabi v0.1.0`.

Small grammar, punctuation, and code style improvements to docs
changelog: Made small grammar, punctuation, and code style improvements to docs
I recently found some places in rust-lang/rust that had lists without spaces after commas, which led me to look for more places, which led me over here to find:
- Some similar lists in code examples that could use spaces after commas to be idiomatic Rust style
- Some lists in documentation text that didn't have spaces after commas, needed an Oxford comma (fight me), or were otherwise misformatted
- Some other grammar improvements in the area of the other changes
These changes should only be in user-facing documentation or output.
Downgrade the await holding lints from correctness
We found a false positive in these lints (see https://github.com/rust-lang/rust-clippy/issues/6353 for more details). As a short-term mitigation, this downgrades the lints from correctness to limit the noise.
changelog: downgrade AWAIT_HOLDING_REFCELL_REF and AWAIT_HOLDING_LOCK to pedantic. From rustup earlier, where I forgot the changlog: deprecate [`panic_params`] (uplifted)
Fix handling of panic calls
