perf(es/parser): Scan template literals with byte search (#12474) **Description:** `scan_template_token` currently scans template bodies one byte at a time. Reuse `byte_search!` with a template-specific match table to skip ordinary text in 32-byte batches while preserving interpolation, escapes, cooked values, and unterminated-template diagnostics. Add fixtures covering batch boundaries, Unicode, lone dollar signs, escaped delimiters, CR/CRLF normalization, tagged escapes, and unterminated templates. Include patch changesets for `swc_ecma_parser` and `swc_core`. **BREAKING CHANGE:** None. **Related issue (if exists):**
