Resolves the effective override decision for a mimeType against a set of
CodecOverrides, or undefined when no override applies (in which case
the caller should fall back to normal support detection).
A 'deny' on any contained codec wins over an 'allow' on another, so an
explicit deny is never silently overridden by an allow elsewhere in the
mimeType.
