rustdoc: fix and refactor HTML rendering a bit
* refactoring: get rid of a bunch of manual `f.alternate()` branches
* not sure why this wasn't done so already, is this perf-sensitive?
* fix an ICE in debug builds of rustdoc
* rustdoc used to crash on empty outlives-bounds: `where 'a:`
* properly escape const generic defaults
* actually print empty trait and outlives-bounds (doesn't work for cross-crate reexports yet, will fix that at some other point) since they can have semantic significance
* outlives-bounds: forces lifetime params to be early-bound instead of late-bound which is technically speaking part of the public API
* trait-bounds: can affect the well-formedness, consider
* makeshift “const-evaluatable” bounds under `generic_const_exprs`
* bounds to force wf-checking in light of #100041 (quite artificial I know, I couldn't figure out something better), see https://github.com/rust-lang/rust/pull/121160#discussion_r1491563816
Add extra indent spaces for rust-playground link
Fixes#120998
Seems add `rustfmt` for this is somehow too heavy,
only adding indent spaces at the starting of each line of code seems good enough.
rustdoc: Correctly handle attribute merge if this is a glob reexport
Fixes#120487.
The regression was introduced in https://github.com/rust-lang/rust/pull/113091. Only non-glob reexports should have been impacted.

rustdoc: offset generic args of cross-crate trait object types when cleaning
Fixes#119529.
This PR contains several refactorings apart from the bug fix.

Use diagnostic namespace in stdlib
This required a minor fix to have the diagnostics shown in third party crates when the `diagnostic_namespace` feature is not enabled. See 5d63f5d8d1 for details. I've opted for having a single PR for both changes as it's really not that much code. If it is required it should be easy to split up the change into several PR's.

[rustdoc] Fix invalid handling for static method calls in jump to definition feature
I realized when working on a clippy lint that static method calls on `Self` could not give me the method `Res`. For that, we need to use `typeck` and so that's what I did in here.
It fixes the linking to static method calls.

It doesn't look quite right, because the lines are too far apart,
and it's not going to be announced by screenreaders as a menu button,
since that's not what the symbol means.
This adds a real tooltip and uses a better drawing of the icon.
Don't merge cfg and doc(cfg) attributes for re-exports
Fixes#112881.
## Explanations
When re-exporting things with different `cfg`s there are two things that can happen:
* The re-export uses a subset of `cfg`s, this subset is sufficient so that the item will appear exactly with the subset
* The re-export uses a non-subset of `cfg`s (e.g. like the example I posted just above where the re-export is ungated), if the non-subset `cfg`s are active (e.g. compiling that example on windows) then this will be a compile error as the item doesn't exist to re-export, if the subset `cfg`s are active it behaves like 1.
### Glob re-exports?
**This only applies to non-glob inlined re-exports.** For glob re-exports the item may or may not exist to be re-exported (potentially the `cfg`s on the path up until the glob can be removed, and only `cfg`s on the globbed item itself matter), for non-inlined re-exports see https://github.com/rust-lang/rust/issues/85043.

Remove mention of rust to make the error message generic.

This is about equally readable, a lot more terse, and stops
special-casing functions and methods.
