This PR makes 2 changes to improve the existing API that are not very useful.
- Remove `(Literal)Parser` and `FlagsParser` and their ASTs
- Add `with_flags(flags_text)` helper to `ParserOptions`
Here are the details.
> Remove `(Literal)Parser` and `FlagsParser` and their ASTs
Previously, the `oxc_regular_expression` crate exposed 3 parsers.
- `(Literal)Parser`: assumes `/pattern/flags` format
- `PatternParser`: assumes `pattern` part only
- `FlagsParser`: assumes `flags` part only
However, it turns out that in actual usecases, only the `PatternParser` is actually sufficient, as the pattern and flags are validated and sliced in advance on the `oxc_parser` side.
The current usecase for `(Literal)Parser` is mostly for internal testing.
There were also some misuses of `(Literal)Parser` that restore `format!("/{pattern}/{flags}")` back and use `(Literal)Parser`.
Therefore, only `PatternParser` is now published, and unnecessary ASTs have been removed.
(This also obsoletes #5592 .)
> Added `with_flags(flags_text)` helper to `ParserOptions`
Strictly speaking, there was a subtle difference between the "flag" strings that users were aware of and the "mode" recognised by the parser.
Therefore, it was a common mistake to forget to enable `unicode_mode` when using the `v` flag.
With this helper, crate users no longer need to distinguish between flags and modes.
