Implement 3D Texture copy for partial depth slices on D3D12

Browse Source 
Note that a slice somehow means a subresource on D3D12. There
are mip slice, array slice, and plane/aspect slice in D3D12.
We reuse the term "slice" for multiple depth of a 3D texture,
although one single depth slice of multiple depth slices is
not a separate subresource of a 3D texture (all these depth
slices for one mip are a separte subresource in 3D texture).

For the reason above, this change also renames "slice" to
"layer" in some functions if "slice" is a layer in that
function. Because a layer is definitely a subresource but a
slice may not be (like a single depth slice of a 3D texture).
