feat(compress): move advanced CCtx parameter init to Rust

Browse Source 
Move ZSTD_CCtxParams_init_advanced and its default-resolution policy into the Rust parameter API while retaining the C public ABI wrapper. Preserve validation, zeroing, and the existing row-match, block-splitter, LDM, and repcode defaults.

Test Plan:\n- cargo clippy --manifest-path rust/Cargo.toml\n- cargo clippy --manifest-path rust/Cargo.toml --benches\n- cargo clippy --manifest-path rust/Cargo.toml --tests\n- cargo +nightly fmt --manifest-path rust/Cargo.toml --all -- --check\n- cargo test --manifest-path rust/Cargo.toml --no-default-features --features compression zstd_compress_params_api\n- make -B -C lib -j2 lib
