Pull request overview

Removes the clippy::equatable_if_let expectation from bumpalo_alloc.rs by refactoring realloc’s in-place grow/shrink checks into Clippy-approved idioms.

Changes:

• Drop clippy::equatable_if_let from the crate-level #![expect(...)] list.
• Replace if let Ok(()) = ... with .is_ok() for grow_in_place / shrink_in_place results in Alloc::realloc.
