ddidderr 0000c6d068 feat(compress): move CCtx size aggregation to Rust ...

Keep ZSTD_sizeof_CCtx's NULL handling, workspace accounting, local-dictionary
sizing, and multithreaded context sizing in C, where the private layouts and
ownership remain visible. Pass only the four resulting size_t values to a Rust
ABI helper, which performs the final ordered additions with C-compatible
wrapping semantics. Add focused coverage for zero, ordinary, and overflowing
component sums.

Test Plan:
- `cargo clippy --manifest-path rust/Cargo.toml --no-default-features --features compression` -- passed before and after formatting
- Same clippy command with `--benches` and `--tests` -- passed before and after formatting
- `cargo +nightly fmt --manifest-path rust/Cargo.toml` -- passed
- `cargo test --manifest-path rust/Cargo.toml --no-default-features --features compression sizeof_cctx` -- passed (6 tests)
- `make -B -C lib -j2 lib` -- passed
- `make -C tests test-rust-lib-smoke` -- passed
- `tests/fuzzer -s4560 -t56 -i57 -v` -- passed
- `make -C tests -j2 test-zstream` -- passed (84 named, 6252 and 9519 randomized)
- `git diff --check` and `git diff --cached --check` -- passed
