improve compiler&tool documenting and re-enable cranelift on CI
First commit addresses the linking issue with compiler crates. Second one ensures that compiler crates are linked correctly (with later commits we added this check for tools as well), allowing us to detect these hard-to-catch bugs on CI. Following three commits cherry-picked from #117328 to re-enable the Cranelift backend on CI.

bootstrap/setup: create hooks directory if non-existing
When running `./x setup` on a local repository I chose to install a `pre-push` git hook, but this happened:
```shell
Would you like to install the git hook?: [y/N] y
error: could not create hook .git/hooks/pre-push: do you already have the git hook installed?
No such file or directory (os error 2)
thread 'main' panicked at src/core/build_steps/setup.rs:462:9:
install_git_hook_maybe(&config) failed with No such file or directory (os error 2)
```
This was caused because the `.git/hooks` directory did not exist in my local repository. Creating it manually and re-running the command works fine.
This PR tests for the above directory and if it does not exist then it _tries_ to create it before hard linking the pre-push hook - we use `fs::create_dir()` and disregard the result (ie. it could fail if the directory was created in the meantime) and proceed to call `fs::hard_link()` all the same.
This was a leftover from when inline asm wasn't universally supported by
the cranelift backend yet. It would cause the optimized inline asm
intrinsics to be avoided for the standard library distributed with
rustup now that we build the cranelift backend by default on nightly for
several tier 1 targets.

Run tidy license checker on more workspaces
The license checker didn't run on several workspaces before this PR. The same applied to the "external package sources" check. There were also two missing lockfiles which I have added now.
They've been deprecated for four years.
This commit includes the following changes.
- It eliminates the `rustc_plugin_impl` crate.
- It changes the language used for lints in
`compiler/rustc_driver_impl/src/lib.rs` and
`compiler/rustc_lint/src/context.rs`. External lints are now called
"loaded" lints, rather than "plugins" to avoid confusion with the old
plugins. This only has a tiny effect on the output of `-W help`.
- E0457 and E0498 are no longer used.
- E0463 is narrowed, now only relating to unfound crates, not plugins.
- The `plugin` feature was moved from "active" to "removed".
- It removes the entire plugins chapter from the unstable book.
- It removes quite a few tests, mostly all of those in
`tests/ui-fulldeps/plugin/`.
Closes#29597.
This reverts commit 1dfb6b162b, reversing
changes made to bcb5798dd8.
That commit broke generating nightly rustc docs. Revert it until we can figure out how to have both, cranelift and docs.
Fix order of implementations in the "implementations on foreign types" section
Fixes#117391.
We forgot to run the `sort_by_cached_key` on this section. This fixes it.
