Merge generics and where predicates and prevent duplicates in where predicates
Part of #104886 (I didn't include bounds from parent trait yet as I think the PR is already big enough).
Also we'll need to run a perf check.
cc `@fmease` since you worked a bit on this.

Don't elide type information when printing E0308 with `-Zverbose`
When we pass `-Zverbose`, we kinda expect for all `_` to be replaced with more descriptive information, for example --
```
= note: expected fn pointer `fn(_, u32)`
found fn item `fn(_, i32) {foo}`
```
Where `_` is the "identical" part of the fn signatures, now gets rendered as:
```
= note: expected fn pointer `fn(i32, u32)`
found fn item `fn(i32, i32) {foo}`
```

Check lifetime param count in `collect_trait_impl_trait_tys`
We checked the type and const generics count, but not the lifetimes, which were handled in a different function.

rustdoc: clean up help and settings button CSS
The old version of this code specified a bunch of different numbers that had to line up just right to get the size it wanted. This version uses flexbox centering, specifies the font size, and lets the browser figure out the rest of the layout automatically.

sparc-struct-abi: work around new tail-call optimization
Upstream LLVM change https://reviews.llvm.org/D138741 introduced some new tail-call smarts for SPARC which broke some of the checks in this test. Rather than adjust the test expectations, we add an extra no-args function that can get tail-called or not without hurting the needs of the test.

Add `type_ascribe!` macro as placeholder syntax for type ascription
This makes it still possible to test the internal semantics of type ascription even once the `:`-syntax is removed from the parser. The macro now gets used in a bunch of UI tests that test the semantics and not syntax of type ascription.
I might have forgotten a few tests but this should hopefully be most of them. The remaining ones will certainly be found once type ascription is removed from the parser altogether.

rustc_ast_lowering: Stop lowering imports into multiple items
Lower them into a single item with multiple resolutions instead.
This also allows to remove additional `NodId`s and `DefId`s related to those additional items.
This avoids calling `early_lint_node` twice.
Note: one `early_lint_node` call had `!pre_expansion` for the second
argument and the other had `false`. The new single call just has
`!pre_expansion`. This results in a reduction of duplicate error
messages in some `ui-fulldeps` tests. The order of some `ui-fulldeps`
output also changes, but that doesn't matter.
