Migrate more things in the new solver to specific `DefId`s

Continuation of rust-lang#145377. I migrated the rest of the types, except aliases.

Aliases are problematic because opaques and associated types share the same type in the new solver. `@jackh726,` `@lcnr,` `@ShoyuVanilla` I'd like to hear ideas here. Anyway, even if we do nothing with them we already got a substantial improvement.

GVN: Ensure indirect is first projection in try_as_place.

I haven't found any report for this bug on existing code, but managed to trigger it with rust-lang#143333

docs(std): add error docs for path canonicalize

This PR adds the missing error documentation for both [Path.canonicalize](https://doc.rust-lang.org/std/path/struct.Path.html#method.canonicalize) and [PathBuf.canonicalize](https://doc.rust-lang.org/std/path/struct.PathBuf.html#method.canonicalize) methods. Since both methods are wappers around [fs::canonicalize](https://doc.rust-lang.org/std/fs/fn.canonicalize.html), the error doc is copied directly from that function.

This makes it faster to find what errors might arise when calling `path.canonicalize` or `path_buf.canonicalize` in the editor itself without needing to drill down to the  `fs::canonicalzie` docs.
Allow static regions in `type_name`.

Fixes rust-lang#146249.

Some `rustc_middle` cleanups

Minor improvements I found while looking through this code.

Fix typo in default.rs

This sentence currently reads:

> Rust implements `Default` for various primitives types.

I think it should just be "primitive types".

Job duration changes

  10. x86_64-gnu-llvm-20-1: 3423.9s -> 3714.4s (8.5%)
How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
