testing: - Remove dependency on relative_path swc_common: - Span's byte positions are now self-contained and `GLOBALS` is not required while parsing. - Changed `Comments` into a trait. - Provide single-threaded implementation of `Comments` - Cargo feature `tty-emiiter` (To remove tty related stuffs ) - Cargo feature `sourcemap` (To remove sourcemap for web assets) - Removed dependency on dashmap swc_ecma_parser: - No duplicated comments. - Removed dependency on once_cell and regex - Add a test suite to visualize and test span of nodes. swc_ecma_utils: - Removed dependency on parser swc: - Remove dependency on derive_more and path-clean - Add multi-threaded implementation of `Comments` swc_ecmascript: - A new crate contains `ast`, `codegen`, `parser`, `utils`, `visit`.
