Increase cargo_metadata version to 0.9.1
`clippy_lints` makes use of `dep_kinds` on `NodeDep` but this was only
added in versoin 0.9.1. Compiling with 0.9.0 will fail because of this.

len_zero: skip ranges if feature `range_is_empty` is not enabled
If the feature is not enabled, calling `is_empty()` on a range is ambiguous. Moreover, the two possible resolutions are unstable methods, one inherent to the range and the other being part of the `ExactSizeIterator` trait.
Since `len_zero` only checks for existing `is_empty()` inherent methods, we only take into account the `range_is_empty` feature.

cargo_dev: add ra-setup
It takes an absolute path to a rustc repo and adds path-dependencies
that point towards the respective rustc subcrates into the Cargo.tomls of
the clippy and clippy_lints crate.
This allows rustc-analyzer to show proper type annotations etc on rustc-internals inside the clippy repo.

Rustup
r? @matthiaskrgr
I finally got to doing the rustup. Sorry for taking so long, I was busy the last few days.
@ebroto FYI: I had to add b6c58f0 to make Clippy pass the rustc test suite.
changelog: none
Update Clippy, RLS, and rustfmt
r? @Dylan-DPC
This makes Clippy test-pass again: 3089c3b
Otherwise this includes bugfixes and a few new lints.

Stabilize str_strip feature
This PR stabilizes these APIs:
```rust
impl str {
/// Returns a string slice with the prefix removed.
///
/// If the string starts with the pattern `prefix`, `Some` is returned with the substring where
/// the prefix is removed. Unlike `trim_start_matches`, this method removes the prefix exactly
/// once.
pub fn strip_prefix<'a, P: Pattern<'a>>(&'a self, prefix: P) -> Option<&'a str>;
/// Returns a string slice with the suffix removed.
///
/// If the string ends with the pattern `suffix`, `Some` is returned with the substring where
/// the suffix is removed. Unlike `trim_end_matches`, this method removes the suffix exactly
/// once.
pub fn strip_suffix<'a, P>(&'a self, suffix: P) -> Option<&'a str>
where
P: Pattern<'a>,
<P as Pattern<'a>>::Searcher: ReverseSearcher<'a>;
}
```

Extend useless conversion
This PR extends `useless_conversion` lint with `TryFrom` and `TryInto`
fixes: #5344
changelog: Extend `useless_conversion` with `TryFrom` and `TryInto`
Register redundant_field_names and non_expressive_names as early passes
Similar names was moved to a pre-expansion pass to solve #2927, so I'm avoiding linting on code from expansion, which makes the dogfood (mostly, see below) pass.
I had to change new_without_default though, and although I understand why it was not triggering before, TBH I don't see why the binding inside the nested `if_chain` is being linted now. Any ideas? (it seems legit though as the code can be changed by the user)
changelog: Register redundant_field_names and non_expressive_names as early passes
Fixes#5356Fixes#5521
Make empty_line_after_outer_attr an early lint
Fixes#5567
Unfortunately I couldn't find a way to reproduce the issue without syn/quote. Considering that most real-world macros use syn and/or quote, I think it's okay to pull them in anyway.
changelog: Fix false positive in [`empty_line_after_outer_attr`]
