Dunqing c59d8b3c9b feat(transformer): support all /regex/ to new RegExp transforms (#5387) 
related: #4754

The implementation port from [esbuild](332727499e/internal/js_parser/js_parser.go (L12820-L12840)). And cover all babel's regexp plugins

---

## The following description was generated by `Graphite` 😋

### TL;DR

Added support for transforming various RegExp features to ensure compatibility with older JavaScript environments.

### What changed?

- Implemented a new `RegExp` transformer to handle unsupported RegExp literal features
- Added options to control different RegExp transformations (e.g., sticky flag, unicode flag, dot-all flag, etc.)
- Updated the transformer to convert unsupported RegExp literals into `new RegExp()` constructor calls
- Added test cases for different RegExp transformations
- Integrated the new RegExp transformer into the existing transformation pipeline

### How to test?

1. Run the existing test suite to ensure no regressions
2. Execute the new RegExp-specific tests in the `tasks/transform_conformance/tests/esbuild-tests/test/fixtures/regexp/` directory
3. Try transforming code with various RegExp features using different target environments to verify correct transformations

Transformation Conformance Test Runner

Execution

This test runner uses the transformation plugin test suite from the babel repository.

The failing test cases are listed in ./babel.snap.md

To get started, run

cargo run -p oxc_transform_conformance

or watch for changes

just watch 'run -p oxc_transform_conformance'

Options

--filter

To filter for a specific test case, apply the --filter path option, e.g.

cargo run -p oxc_transform_conformance -- --filter react/arrow-functions

--exec

The babel test suite contains many exec.js files, they need to be executed by a runtime.

Bun is the preferred way to execute these tests, which you may install them via https://bun.sh/docs/installation.

Once bun is installed, apply the --exec flag:

cargo run -p oxc_transform_conformance -- --exec

The failing test cases are listed in ./babel_exec.snap.md.
