Fix macOS and Windows installers when rust-docs is not available.
This fixes the macOS `.pkg` and Windows `.msi` installers to work when rust-docs is not available. If the rust-docs component is not built, then the installer would fail. This adds the rust-docs component to the filtering mechanism so that the rust-docs line of the distribution definition aren't included.
I tested installing and uninstalling both with and without the rust-docs component available.
This happens on the aarch64-apple-darwin distribution provided by rust-lang since we currently disable the rust-docs component due to long build times. An alternate solution would be to just enable the rust-docs component on aarch64-apple-darwin since there are faster build systems.

Migrate remainder of rustc_ty_utils to `SessionDiagnostic`
This moves the remaining errors in `rust_ty_utils` to `SessionsDiagnostic`.

Instantiate instead of erasing binder when probing param methods
Fixes#108836
There is a really old comment saying that a `WhereClauseCandidate` probe candidate "should not contain any inference variables", but I'm not really confident that that comment applies anymore. In contrast, other candidates that we assemble during method probe contain inference variables in their substitutions (e.g. `InherentImplCandidate`)...
Since this change is made only to support a nightly feature, I'm happy to gate the new behavior behind this feature flag or discuss it further.
r? types
The shadowing lead to an incorrect comparison. Rename it and compare it
properly. compiler-errors told me that I should just include the fix
here without a test.
Better diagnostic when pattern matching tuple structs
Fixes#108284
When trying to pattern match a tuple struct we might get a flawed error message if there are missing fields. E.g.
```
let x = Foo(100, 200);
if let Foo { 0: bar } = x { ... }
```
Produces this error:
```
error[E0769]: tuple variant `Foo` written as struct variant
--> hello.rs:5:12
|
5 | if let Foo { 0: foo } = x {
| ^^^^^^^^^^^^^^
|
help: use the tuple variant pattern syntax instead
|
5 | if let Foo(_, _) = x {
| ~~~~~~
```
Which doesn't highlight that we can still use the struct syntax but we need to fill missing fields. This pr changes this error to:
```
error[E0027]: pattern does not mention field `1`
--> hello.rs:5:12
|
5 | if let Foo { 0: foo } = x {
| ^^^^^^^^^^^^^^ missing field `1`
|
help: include the missing field in the pattern
|
5 | if let Foo { 0: foo, 1: _ } = x {
| ~~~~~~~~
help: if you don't care about this missing field, you can explicitly ignore it
|
5 | if let Foo { 0: foo, .. } = x {
| ~~~~~~
```

resolve: Preserve reexport chains in `ModChild`ren
This may be potentially useful for
- avoiding uses of `hir::ItemKind::Use` (which usually lead to correctness issues)
- preserving documentation comments on all reexports, including those from other crates
- preserving and checking stability/deprecation info on reexports
- all kinds of diagnostics
The second commit then migrates some hacky logic from rustdoc to `module_reexports` to make it simpler and more correct.
Ideally rustdoc should use `module_reexports` immediately at the top level, so `hir::ItemKind::Use`s are never used.
The second commit also fixes issues with https://github.com/rust-lang/rust/pull/109330 and therefore
