Ahmed Ibrahim 8dd0a08160 Request transparent huge pages for Cargo and eligible Bazel rustc jobs (#47962) ...

## What changed

- Default `MALLOC_CONF` to `thp:always` for Cargo child processes, including tests and `cargo run`, while preserving an explicitly set value, even if empty.
- Patch `rules_rust` to request transparent huge pages for `codex-rs/` compilation with Linux GNU `rustc` on x86_64 and aarch64. Check policy on the execution worker and enable the setting only when seccomp is disabled, transparent huge pages are permitted, and no allocator, preload, or sanitizer configuration conflicts are detected. Leave the environment unchanged when policy cannot be determined.
