Align offset to 512 when writing into depth stencil textures on some platforms

On the D3D12 platforms that don't support programmable sample positions,
the source box specifying a portion of the depth texture must all be 0,
or an error and a device lost will occur. This patch adds a workaround
for this issue by alignning the offset of internal staging buffer to 512
when calling Queue.WriteTexture() with depth stencil textures
