[TextureD3D12] Add ASSERT verifying safety of concurrent read access

For concurrent read access to be safe on D3D12, textures must be
implicitly decayable to the COMMON state at all times that a read access
is occurring on the Texture. Otherwise, there is a risk that the Texture
is modified by one read access as part of modifying its compression
while another read access is reading the data being modified.
