fix(parser): add modifier ordering validation (TS1029) (#19024)

## Summary

- Replace `check_for_duplicate_modifiers` with `check_modifier` that
handles both duplicate detection and ordering validation in a single
match statement, following TypeScript's `checkGrammarModifiers` logic
- Correctly reports TS1029 (`'x' modifier must precede 'y' modifier`)
for out-of-order class member modifiers
- Remove redundant static/readonly ordering check for index signatures
in `class.rs` (now handled centrally)
- Remove unused `contains_all_flags` method from `Modifiers`

**Babel**: Negative passed 1660 → 1665 (+5)
**TypeScript**: Negative passed 1515 → 1529 (+14)
