Subject: [PATCH] refactor(allocator): fix `legacy_numeric_constants` clippy
 warnings (#21231)

Same as stack starting at #21210.

`bumpalo_alloc.rs` was copied directly from `bumpalo`. `bumpalo` supports much older Rust versions than Oxc does, so uses patterns which are flagged by Clippy in more recent versions. #20963 silenced these clippy errors/warnings with a large `#[expect]` block at the top of the file.

This stack of PRs fixes these warnings and removes the `#[expect(clippy:...)]` comments. All PRs in this stack were generated by Claude.  I had him split them into 1 PR per clippy rule so that I could review each in isolation - some of the changes, especially around pointers, are quite subtlle.
