feat(rust): port Huffman compression

Move Huffman table construction, table serialization, and one- and
four-stream payload encoding from huf_compress.c into the Rust compatibility
archive.  The declaration-only C shim preserves the existing internal ABI,
so the remaining C compressor can call the migrated implementation unchanged.

The translation keeps CTable layouts, workspace checks, repeat-table
selection, and bitstream output compatible with the original encoder.  This
lets native C consumers exercise the Rust implementation through libzstd.

Test Plan:
- cargo clippy, cargo clippy --benches, and cargo clippy --tests
- cargo +nightly fmt and cargo test --all-targets (88 passed)
- cargo check --no-default-features --features compression
- rebuild and run tests fuzzer, zstreamtest, and invalidDictionaries
- compare tables, headers, and 1X/4X streams with a renamed pristine C build
