vfs: add generic nocmtime mount flag

Add the infrastructure to support a generic nocmtime mount flag. Like
MS_NOATIME/MNT_NOATIME this can be used to support the mount option in
file systems without having to touch each file system.

This will be used to provide a priviledged indication that unpriviledged
apps can safely use O_NOCMTIME to prevent cmtime updates without harm.
