perf(transformer/regexp): avoid copying string data and temp String

[overlookmotel]

Avoid temp String and copying string data by:

1. Reusing existing Atom where possible, instead of copying the string data and creating a new Atom.
2. Use format_atom! macro (introduced in feat(span): introduce format_atom! macro #10722) to avoid creating a temporary String when converting oxc_regular_expression::Pattern to a string.
