Subject: macos: normalize unicode file names in forward mode

Summary: Store as NFC, read as NFD.

This commit resolves https://github.com/rfjakob/gocryptfs/issues/850
by addressing Unicode normalization mismatches on macOS between NFC
(used by CLI tools) and NFD (used by GUI apps). The solution is inspired
by Cryptomator's approach ( https://github.com/cryptomator/cryptomator/issues/264 ).

Forward mode on MacOS now enforces NFC for storage but presents NFD
as recommended by https://developer.apple.com/library/archive/qa/qa1173/_index.html
and https://github.com/macfuse/macfuse/wiki/File-Names-(Unicode-Normalization-Forms) .

See https://github.com/rfjakob/gocryptfs/pull/949 for more info.

This commit does nothing for reverse mode as it is not clear if
anything can be done. Reverse mode can not influence how the
file names are stored, hence mapping normalized names back to
what is actually on disk seems difficult.
