Subject: [PATCH] DebugInfo: Remove DIObjCProperty attribute accessors, NFC

There's only one user of the various `DIObjCProperty::is*Property()`
accessors -- `DwarfUnit::constructTypeDIE()` -- and it's just using the
reverse logic to reconstruct the bitfield.  Drop this API and simplify
the only caller.
