Selectively enable D3D11 on Intel GPUs.

Selectively enable D3D11 on Intel GPUs.

devices, enable D3D11 on newer drivers. Leave older drivers, in this
case prior to 8.16, disabled for now.

PTAL Ken, we should probably keep an eye out for perf regressions or stability
problems when this goes live.

might also give a heads up to the Perf team. +tonyg
