Add VDENC(lowpower mode) support for QSV h264 and HEVC
with the limitation of MSDK API verion greater than 1.15.
It's an experimental function(like lowpower in vaapi) with
some limitations:
- CBR/VBR require HuC which should be explicitly loaded via i915
module parameter(i915.enable_guc=2 for >=4.16)
- HEVC VDENC was supported >= ICE LAKE
use option "-low_power 1" to enable VDENC.

Looks good, would be great if you could update the documentation about
it since it seems to require some additional setup.
I'd merge it Monday if nobody is against it.
