fix(compress): gate MT frame callback by build feature

Browse Source 
The MT frame-progression callback is only referenced when ZSTD_MULTITHREAD is enabled. Keep its definition under the same configuration guard so single-threaded library, test, and decode-corpus builds do not report an unused static function while the MT callback remains available to the Rust dispatch bridge.

Test Plan:

- git diff --cached --check

- Capped full tests passed before this warning-only guard

- Capped native rebuild and smoke rerun pending
