Sandbox file rules on Windows and macOS now match paths regardless of letter case.

On Windows and macOS, sandbox filesystem allow/deny glob rules now also match using Unicode case-folding (NFD normalize, lowercase, uppercase, NFC normalize) in addition to exact matching, so differently-cased paths referring to the same file are treated consistently.
