revert(swc_common): Revert sourcemap multibyte mapping clamp (#11919) **Description:** Reverts #11918 because the source map builder clamp is not the correct fix for the Next.js/MUI source map panic. This removes the `normalize_sourcemap_pos` helper, its use in `build_source_map`, and the regression test added by that PR, restoring the previous source map assertion behavior. This PR also replaces the original changeset with a revert changeset for `swc_common` and `swc_core`. Validation: - `git submodule update --init --recursive` - `cargo fmt --all` - `cargo test -p swc_common` - `cargo clippy --all --all-targets -- -D warnings` **Related issue:** Reverts #11918

fix(swc_common): Fix sourcemap panic for multibyte mapping positions (#11918) **Description:** This makes source map generation robust when a raw mapping points inside a UTF-8 multibyte character. The builder now normalizes such positions to the start of the character before calculating UTF-16 source columns, so assertion-enabled builds do not panic on mappings like the MUI box-drawing comment case seen in Next.js CI. The existing `calc_utf16_offset` assertions are kept intact; only the source map builder input is normalized. The regression test covers both a 3-byte box-drawing character and a 4-byte emoji interior byte position, and verifies that emitted source columns point at the character start. Validation: - `git submodule update --init --recursive` - `cargo test -p swc_common --features sourcemap source_map_clamps_mappings_inside_multibyte_chars` - `cargo test -p swc_common source_map` - `cargo test -p swc_common` - `cargo fmt --all` - `cargo clippy --all --all-targets -- -D warnings` - Next.js PR 94157 scratch checkout: rebuilt assertion native with patched `swc_common 21.0.1`, then `material-ui.test.ts` dev-webpack e2e passed without the `BytePos(658)` panic.
