This method is used to generate headers for embedding files into the binary (think about the new `#embed` feature in C23 and C++26). While the stringification step itself was plenty fast, it then proceeded to wrap everything using the `textwrap` module. `textwrap` is *very* slow, as it's apparently optimized for human text. This patch reimplements the wrapping logic using a simple regex, resulting in a tremendous speed improvement (~6x), and switches to `map` for the stringification itself (thanks Rémi!) It also removes a (practically) unused argument, `initial_indent`. The generated files are pretty much the same, with a tiny difference in line length (for some reason the old logic overshot the requested line length)
