D3D12: Re-enable the workaround for T2T copy issue on Intel GPUs 

This patch re-enables the workaround for T2T copy issue on Intel
GPUs as we have found there are still other issues about T2T copies
on latest Intel D3D12 driver when we investigate the WebGPU CTS
failures on Intel Gen9 and Gen9.5 GPUs.
