add -Zui-testing to rustdoc
Before we depend on the `rustdoc-ui` tests some more, let's make rustdoc act the same as the compiler when they're actually being executed.

constraints:
- clean/inline.rs needs this map to fill in traits when inlining
- fold.rs needs this map to allow passes to fold trait items
- html/render.rs needs this map to seed the Cache.traits map of all
known traits
The first two are the real problem, since `DocFolder` only operates on
`clean::Crate` but `clean/inline.rs` only sees the `DocContext`. The
introduction of early passes means that these two now exist at the same
time, so they need to share ownership of the map. Even better, the use
of `Crate` in a rustc thread pool means that it needs to be Sync, so it
can't use `Lrc<Lock>` to manually activate thread-safety.
`parking_lot` is reused from elsewhere in the tree to allow use of its
`ReentrantMutex`, as the relevant parts of rustdoc are still
single-threaded and this allows for easier use in that context.
rustdoc: Remove generated blanket impls from trait pages
#53801 only deduped the generated blanket impls but they shouldn't be displayed at all because the original blanket impl is already in the "Implementors" section. This also removes the impls from the sidebar.
Fixes#53689
r? @QuietMisdreavus
rustc_typeck: turn `where Type:,` into a WF(Type) predicate, instead of ignoring it.
Fixes#53696, assuming crater doesn't catch anyone using this syntax already.
Allowing an empty list of bounds in the grammar was done for the benefit of macro authors, most of which would *probably* be using it for bounds on type parameters, which are always WF.
