URLPattern: Translate path-to-regexp regex generation to c++.
This CL translates the path-to-regexp regular expression generator from
typescript to c++. Its based on the code here:
https://github.com/pillarjs/path-to-regexp/blob/125c43e6481f68cc771a5af22b914acdb8c5ba1f/src/index.ts#L532-L596
We deviate from the path-to-regexp code in a couple minor ways. First
we only return a list of group names instead of the full "key" objects
containing prefix, suffix, etc. Second, the code structure is reordered
a bit to make early-return style more readable.
