perf(ext/urlpattern): optimize URLPattern.exec (#20170)

This PR optimizes `URLPattern.exec` 

- Use component keys from constructor instead of calling it on every
`.exec`. AFAIK keys should always be
`protocol`,`username`,`password`,`hostname`,`port`,`pathname`,`search`,`hash`.
Haven't looked much into it but I think it's safe to define these
outside the constructor as well.
- Add a fast path for `/^$/u` (default regexp) and empty input
- Replaced `ArrayPrototypeMap` & `ObjectFromEntries` with a `for` loop.
