Lint simple expressions in `manual_filter_map`, `manual_find_map`

changelog: Lint simple expressions in [`manual_filter_map`], [`manual_find_map`]

The current comparison rules out `.find(|a| a.is_some()).map(|b| b.unwrap())` because `a` being a reference can effect more complicated expressions, this adds a simple check for that case and adds the necessary derefs

There's some overlap with `option_filter_map` so `lint_filter_some_map_unwrap` now returns a `bool` to indicate it linted

782b484b79 Fix ICE in sugg::DerefDelegate with (named) closures
rustc comiler internals helpfully tell us how to fix the issue:

  to get the signature of a closure, use `substs.as_closure().sig()` not `fn_sig()`

Fixes ICE in #9041

Fix `#[expect]` for most clippy lints

This PR fixes most `#[expect]` - lint interactions listed in rust-lang/rust#97660. [My comment in the issue](https://github.com/rust-lang/rust/issues/97660#issuecomment-1147269504) shows the current progress (Once this is merged). I plan to work on `duplicate_mod` and `multiple_inherent_impl` and leave the rest for later. I feel like stabilizing the feature is more important than fixing the last few nits, which currently also don't work with `#[allow]`.

a4130e1612 Auto merge of #8355 - Jarcho:explicit_auto_deref_2, r=flip1995
Add lint `explicit_auto_deref` take 2

fixes: #234
fixes: #8367
fixes: #8380

Still things to do:

* ~~This currently only lints `&*<expr>` when it doesn't trigger `needless_borrow`.~~
* ~~This requires a borrow after a deref to trigger. So `*<expr>` changing `&&T` to `&T` won't be caught.~~
* The `deref` and `deref_mut` trait methods aren't linted.
* Neither ~~field accesses~~, nor method receivers are linted.
* ~~This probably shouldn't lint reborrowing.~~
* Full slicing to deref should probably be handled here as well. e.g. `&vec[..]` when just `&vec` would do

try reading rust-version from Cargo.toml

Cargo.toml can contain a field `rust-version`, that acts like a MSRV of
clippy.toml file: https://doc.rust-lang.org/cargo/reference/manifest.html#the-rust-version-field
This will try to read that field and use it, if the clippy.toml config
has no `msrv` entry

`trivially_copy_pass_by_ref` fixes

fixes #5953
fixes #2961

The fix for #5953 is overly aggressive, but the suggestion is so bad that it's worth the false negatives. Basically three things together:
* It's not obviously wrong
* It compiles
* It may actually work when tested

changelog: Don't lint `trivially_copy_pass_by_ref` when unsafe pointers are used.
changelog: Better track lifetimes when linting `trivially_copy_pass_by_ref`.

6384765665 parse Cargo.toml file in ui-cargo tests
compiletest_rs is not meant to test full cargo projects, but instead
only files.
So we need to parse the `Cargo.toml` file ourself and set the
corresponding environment variable. In this case we just set
`CARGO_PKG_RUST_VERSION`, nothing more. But, of course, this can be
extended.
