get_maintainer: add ** glob pattern support
Add support for the ** glob operator in MAINTAINERS F: and X: patterns,
matching any number of path components (like Python's ** glob).
The existing * to .* conversion with slash-count check is preserved. **
is converted to (?:.*), a non-capturing group used as a marker to bypass
the slash-count check in file_match_pattern(), allowing the pattern to
cross directory boundaries.
This enables patterns like F: **/*[_-]kunit*.c to match files at any depth
in the tree.
