GH-115060: Speed up `pathlib.Path.glob()` by removing redundant regex matching (#115061)

When expanding and filtering paths for a `**` wildcard segment, build an `re.Pattern` object from the subsequent pattern parts, rather than the entire pattern, and match against the `os.DirEntry` object prior to instantiating a path object. Also skip compiling a pattern when expanding a `*` wildcard segment.
