On Intel Gen9 (SKL) and Gen9.5 (KBL, CFL, CML) GPUs with latest Intel D3D12 driver (27.20.100.9316), there is a bug in the command CopyTextureRegion() when we want to do the texture-to-texture copy with the formats whose texel block size < 4 bytes and source mipmap level > destination mipmap level. This patch adds a workaround for this driver bug by implementing the functionality of the T2T copy with one T2B copy and one B2T copy.
