Disable `integer_to_ptr_transmutes` suggestion for unsized types
This PR disables the machine-applicable `integer_to_ptr_transmutes` lint suggestion for unsized types, as [`std::ptr::with_exposed_provenance`](https://doc.rust-lang.org/std/ptr/fn.with_exposed_provenance.html) requires sized types.
We should probably mention [`std::ptr::from_raw_parts`](https://doc.rust-lang.org/std/ptr/fn.from_raw_parts.html) when it becomes stable.

No source fixes
This PR started as a fix for a rendering bug that [got noticed in #143661](https://github.com/rust-lang/rust/pull/143661#discussion_r2199109530), but turned into a fix for any rendering bugs related to files with no source.
- Don't add an end column separator after a file with no source
- Add column separator before secondary messages with no source
- Render continuation between no source labels

Remove unnecessary `[dependencies.unicode-properties]` entries.
The Cargo style guide says to put dependencies on a single line if they fit.

Use captures(address) instead of captures(none) for indirect args
While provenance cannot be captured through these arguments, the address / object identity can.
Fixes https://github.com/rust-lang/rust/issues/137668.

rustdoc: a few micro-optimizations targeted at build_impl
Unsure if these will be anything substantial, but the first one at least should git rid of quite a few branches, second one unsure if it's worth it.

Introduce a `[workspace.dependencies`] section in the top-level `Cargo.toml`
It lets us avoid a lot of repetition of crate versions, etc.
I've just done a few as a start. Many more can be done in follow-ups.

Region inference: Use outlives-static constraints in constraint search
Revise the extra `r: 'static` constraints added upon universe issues to add an explanation, and use that explanation during constraint blame search. This greatly simplifies the region inference logic, which now does not need to reverse-engineer the event that caused a region to outlive `'static`.
This cosmetically changes the output of two UI tests. I blessed them i separate commits with separate motivations, but that can of course be squashed as desired. We probably want that.
The PR was extracted out of rust-lang/rust#130227 and consists of one-third of its functional payload.

Access less HIR attributes from typeck
Typeck relies on attributes to modify its own behaviour. This is a problem, as this means that `typeck(some function)` may depend on the span and doc-comments of many other functions.
This PR attempts to reduce such accesses to attributes. This yields to a sizeable perf improvement: https://github.com/rust-lang/rust/pull/144841#issuecomment-3153339771
Fixes https://github.com/rust-lang/rust/issues/124352
