  Reland: [NFC][Support] Implement slash-agnostic path matching in GlobPattern (#206251)

Add a SlashAgnostic option to GlobPattern to allow matching path
separators
(both forward slashes and backslashes) agnostically.

When enabled:
- We conservatively reduce the plain prefix and suffix by treating path
  separators as metacharacters. This ensures that path separators are
  matched via the slash-agnostic state machine rather than plain string
  comparison.
- Brackets containing slashes are adjusted to match both separators.
- Character comparisons in the state machine (matchChar) treat '/' and
  '\' as equivalent.

For #149886.

Reland of #202854 incorrectly reverted in #205409.
