Extend loading of Fluent bundles so that bundles can be loaded from the
sysroot based on the language requested by the user, or using a nightly
flag.
Sysroot bundles are loaded from `$sysroot/share/locale/$locale/*.ftl`.

This commit updates the signatures of all diagnostic functions to accept
types that can be converted into a `DiagnosticMessage`. This enables
existing diagnostic calls to continue to work as before and Fluent
identifiers to be provided. The `SessionDiagnostic` derive just
generates normal diagnostic calls, so these APIs had to be modified to
accept Fluent identifiers.
In addition, loading of the "fallback" Fluent bundle, which contains the
built-in English messages, has been implemented.
Each diagnostic now has "arguments" which correspond to variables in the
Fluent messages (necessary to render a Fluent message) but no API for
adding arguments has been added yet. Therefore, diagnostics (that do not
require interpolation) can be converted to use Fluent identifiers and
will be output as before.
`MultiSpan` contains labels, which are more complicated with the
introduction of diagnostic translation and will use types from
`rustc_errors` - however, `rustc_errors` depends on `rustc_span` so
`rustc_span` cannot use types like `DiagnosticMessage` without
dependency cycles. Introduce a new `rustc_error_messages` crate that can
contain `DiagnosticMessage` and `MultiSpan`.

Don't lint `cast_ptr_alignment` when used for unaligned reads and writes
fixes#2881
Ideally this would trace the usage of the value rather than only looking at the parent expression, but that would require dataflow analysis. e.g.
```rust
let x = ptr as *const u16;
c.read_unaligned(x);
```
Arch specific intrinsic functions need to be checked for ones which could take an unaligned pointer. This can be another PR.

Rework `undocumented_unsafe_blocks`
fixes: #8264fixes: #8449
One thing came up while working on this. Currently comments on the same line are supported like so:
```rust
/* SAFETY: reason */ unsafe {}
```
Is this worth supporting at all? Anything other than a couple of words doesn't really fit well.

We're collecting our changelog from pull request descriptions.
If your PR only includes internal changes, you can just write
`changelog: none`. Otherwise, please write a short comment
explaining your change. Also, it's helpful for us that
the lint name is put into brackets `[]` and backticks `` ` ` ``,
e.g. ``[`lint_name`]``.
If your PR fixes an issue, you can add "fixes #issue_number" into this
PR description. This way the issue will be automatically closed when
your PR is merged.
If you added a new lint, here's a checklist for things that will be
checked during review or continuous integration.
- \[ ] Followed [lint naming conventions][lint_naming]
- \[ ] Added passing UI tests (including committed `.stderr` file)
- \[ ] `cargo test` passes locally
- \[ ] Executed `cargo dev update_lints`
- \[ ] Added lint documentation
- \[ ] Run `cargo dev fmt`

order to get feedback.

Closes#8591
I'm already sorry for the massive diff 😅
changelog: New lint [`empty_structs_with_brackets`]
Remove deps
This remove both `regex` and `cargo_metadata` as dependencies making `clippy_dev` compile ~3x faster (~46s -> ~16s locally). `cargo_metadata` was used to extract the `version` field from `Cargo.toml`, which is done trivially without that. `regex` was used to parse `define_clippy_lint` in `update_lints` which is now done using `rustc_lexer`. This isn't any simpler, but it compiles ~15s faster and runs ~3x faster (~2.1s -> ~0.7s locally).
The next biggest offenders to compile times are `clap` and `winapi` on windows. `clap` could be removed, but re-implementing enough is probably more work than it's worth. `winapi` is used by `opener` and `walkdir` so it's stuck there.

Handle relative paths in module_files lints
The problem being that when clippy is run in the project's directory `lp` would be a relative path, this wasn't caught by the tests as there `lp` is an absolute path. Being a relative path it did not start with `trim_src_path` and so was ignored
Also allowed the removal of some `.to_os_string`/`.to_owned`s

Remember mutability in `DefKind::Static`.
This allows to compute the `BodyOwnerKind` from `DefKind` only, and
removes a direct dependency of some MIR queries onto HIR.
As a side effect, it also simplifies metadata, since we don't need 4
flavours of `EntryKind::*Static` any more.
Add `crate_in_macro_def` lint
This PR adds a lint to check for `crate` as opposed to `$crate` used in a macro definition.
I think this can close#4798. That issue focused on the case where the macro author "imports something into said macro."
But I think use of `crate` is likely to be a bug whether it appears in a `use` statement or not. There could be some use case I am failing to see, though. (cc: `@nilscript` `@flip1995)`
