D3D12: Simplify the mapping logic.

This also removes the reliance on BufferBase::IsMapped to know whether
to unmap on destroy. This call was confusing because it was used by the
D3D12 backend to know if its own storage was mapped, but semantically
seemed to check for Buffer::State::Mapped (and not MappedAtCreation).
