fix(minifier): validate RegExp patterns before marking as pure ( #18125 )
...
## Summary
Invalid RegExp patterns like `RegExp("[")` or invalid flags like `RegExp("a", "xyz")` throw `SyntaxError` at runtime, but the minifier was incorrectly removing them.
This change uses `oxc_regular_expression` to validate patterns at compile time:
- Valid patterns are marked as pure and can be removed when unused
- Invalid patterns or non-literal arguments are kept (preserving runtime errors)
### Behavior
| Input | Valid? | Removed? |
|-------|--------|----------|
| `RegExp()` | ✅ | ✅ |
| `RegExp('a', 'g')` | ✅ | ✅ |
| `RegExp(/foo/)` | ✅ | ✅ |
| `RegExp('[')` | ❌ | ❌ (throws SyntaxError) |
| `RegExp('a', 'xyz')` | ❌ | ❌ (throws SyntaxError) |
| `RegExp(variable)` | ? | ❌ (can't determine) |
Fixes #18050
## Test plan
- [x] Updated existing tests to reflect correct behavior
- [x] Added tests for invalid patterns and flags
- [x] `cargo test -p oxc_minifier` passes
- [x] `cargo test -p oxc_ecmascript` passes
