Subject: Remove MTLManagedObjectAdapter.h

We are using an outdated version of Mantle which leverages NSConfinementConcurrencyType,
an enum which has been deprecated with no replacement as of macOS 10.11.
The actual solution to this problem is to upgrade Mantle, but for now
we just stop building the offending adapter.
