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 rust-lang#29597.

Try to update parser/event doc

`TokenSource` and `TreeSink` has been refactored as part of rust-lang#10765, they no longer exist in code repo. This pr tries to remove them from event module level comment to prevent confusion.

Improve check for include macro

Add config for preferring / ignoring prelude modules in find_path

Mirrors `PathSegment's` version, except that it always generates a
turbofish

`add_type_ascription` is still left as-is since it's a different assist

Way for setting and removing the type ascription of a let stmt

Due to the way the current tree mutation api works, we need to collect
changes before we can apply them to the real syntax tree, and also can only
switch to a file once.

`destructure_tuple_binding_in_sub_pattern` also gets migrated even
though can't be used.

minor: Make "Expand macro" command title more explicit

Closes [rust-lang#15856](rust-lang/rust-analyzer#15856).

I opted for "caret", since it's the better term (cursor is the mouse), but I'm not sure how popular it is these days.

internal: Include toml files in the vfs

minor: Allow multiple snippet edits in a `TextDocumentEdit`

Explicitly[^1] allow a single `TextDocumentEdit` to have multiple `SnippetTextEdit`s. This allows things like renaming extracted variables and functions without having to go through a separate rename step. For an example of what this looks like, see the video in [this comment](microsoft/vscode#145374 (comment)).

The behavior described here lines up with [what VSCode does](https://github.com/microsoft/vscode/blob/bdc113ffe148a92d0e1a8ec34b12c44ea0b73f29/src/vscode-dts/vscode.d.ts#L3728-L3731), and presumably what the eventual LSP behavior will be.

[^1]: This was technically the case before rust-lang#15269, a single `TextDocumentEdit` always had multiple edits which were `InsertTextFormat.Snippet` as all of the edits were marked as being snippets, even if there weren't any tab stops or placeholders.

docs: fix VS Code setting samples

Fix invalid JSONC examples (missing double quotes) in VS Code's `settings.json` .
Thank you.

Needed so that the `tuple_pat` node gets added to the syntax tree,
which is required as we're using structured snippets.

Diagnose missing assoc items in trait impls

Assist wasn't applicable when the let statement was missing a pattern
before, so we should do the same now.

internal: Migrate assists to the structured snippet API, part 4

Continuing from rust-lang#15260

Migrates the following assists:
- `add_turbo_fish`
- `add_type_ascription`
- `destructure_tuple_binding`
- `destructure_tuple_binding_in_subpattern`

I did this a while ago, but forgot to make a PR for the changes until now. 😅

fix: Diagnose everything in nested items, not just def diagnostics

Turns out we only calculated def diagnostics for these before (was wondering why I wasn't getting any type mismatches)

Fix builtin line! expansion

`concat` expects only literals, not whole syntax nodes, so we need to expand as such

code: expose workspaces to other extensions; remove `addProject` command

This (mostly red) PR does three things:
- Exposes two methods to companion extensions (`setWorkspaces` and `notifyRustAnalyzer`).
    - `setWorkspaces` is needed to update `linkedProjects` _without_ writing workspace/global configuration.
    - `notifyRustAnalyzer` to get the server to pull the new configuration.
- Makes `Ctx` implement `RustAnalyzerExtensionApi` to prevent accidental regressions.
- Remove `rust-analyzer.addProject`, as that will live in a buck2 companion extension. No need for that to be in rust-analyzer!

I can see the utility of combining `notifyRustAnalyzer` and `setWorkspaces` into a single method (`updateWorkspacesAndNotify()`?), but I don't feel strongly about this. My feeling is that this API could be easily changed in the future.
