Add VDENC(lowpower mode) support for QSV h264 and HEVC

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 linux kerner version >= 4.16)
- HEVC VDENC was supported >= ICE LAKE

use option "-low_power 1" to enable VDENC.

[V2]: modified the commit message and option comments, use AV_OPT_TYPE_BOOL
to replace AV_OPT_TYPE_INT.

Should it be under "-strict experimental" then?

This remark belongs below the "---" line, so it doesn't show up in the
actual final commit.

(Right here.)

Same here.

Thanks for your review, and I'm so sorry for these mistakes.
