Since array and slice constants are now lowered to array and slice
patterns, `non_scalar_compare` was only called for string comparisons.
This specializes it to strings, renames it, and removes the unused
array-unsizing logic.

This also updates some outdated doc comments.
- Should be same as absolute in UEFI since there are no symlinks.
- Also each absolute path representation should be unique according to
  the UEFI specification.

- UEFI does not have symlinks. So lstat and stat should behave the same.

UEFI does not have specific modes for create_new, truncate and append.
So those need to to be simulated after opening the file.

Implement some basics in UEFI fs

- Just getting some basics out of the way while waiting for rust-lang#138236 to be merged.
- Adds `fs::canonicalize`. Should be same as absolute in case of UEFI since there is no symlink support and absolute path is guaranteed to be uniqe according to spec.
- Make `fs::lstat` same as `fs::stat`. Should be same since UEFI does not have symlink support.
- Implement `OptionOptions`.

remove remnants of const_box feature

This feature requires major design work, and the few methods it gates currently aren't actually useful. Let's reset to a clean slate so when a design materializes, we can start from scratch.

Closes rust-lang#92521 by removing the feature it tracks.

match lowering cleanup: remove unused unsizing logic from `non_scalar_compare`

Since array and slice constants are now translated to array and slice patterns, `non_scalar_compare` is only used for string comparisons. This specializes it to strings, renames it, and removes the unused array-unsizing logic.

This also updates the doc comments for  `thir::PatKind::Constant` and `TestKind::Eq`, which referred to them being used for slice references.

resolve: Avoid remaining unstable iteration

Continuation of rust-lang#138580.
This should be the performance sensitive part.
