Preparation for #6141
`oxc_regular_expression` can already parse and validate both `/regexp-literal/` and `new RegExp("string-literal")`.
But one thing that is not well-supported was reporting `Span` for the `RegExp("string-literal-with-\\escape")` case.
For example, these two cases produce the same `RegExp` instances in JavaScript:
- `/\d+/`
- `new RegExp("\\d+")`
For now, mainly in `oxc_linter`, the latter case is parsed with `oxc_parser` -> `ast::literal::StringLiteral` AST node -> `value` property.
At this point, escape sequences are resolved(!), `oxc_regular_expression` can handle aligned `&str` as an argument without any problem in both cases.
However, in terms of `Span` representation, these cases should be handled differently because of the `\\` in string literals...
As a result, the parsed AST's `Span` for `new RegExp("string-literal")` is not accurate if it contains escape sequences.
