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.

Fixes high memory usage and prevents over allocation of the frames via
proper unref.
Can be checked as:
-hwaccel qsv -c:v h264_qsv -i ../h264-conformance/CANL2_Sony_E.jsv -c:v
h264_qsv -b:v 2000k -y qsv.mp4
we need to make sure that memory allocation for Y/UV planes is continuous and re-used from a
pool

Current implementations of qsv components incorrectly work with async level, they
actually try to work in async+1 level stepping into MFX_WRN_DEVICE_BUSY and polling
loop. This change address this misbehaviour.

Use a common way to control target_usage, keeping consistent with vaapi
encoders. The private option preset is kept only for compatibility.

Currently it always shows "Selected ratecontrol mode is not supported
by the QSV runtime. Choose a different mode", but sometimes it is not
accurate.

Hypothetical Reference Decoding (HRD) model assumes that data flows
into a buffer of the fixed size BufferSizeInKB with a constant bitrate.
Smaller BufferSizeInKB means smaller frame size variations,
but more difficult to maintain HRD.

Fill out the default/unset parameters with ones actually in use.
Matches the current MediaSDK example code.

This will allow implementing the allocator more fully, which is needed
by the HEVC encoder plugin with video memory input.

For encoding, this avoids modifying the input surface, which we are not
allowed to do.
This will also be useful in the following commits.

The QSV runtime expects the sync point address passed to
MFXVideoENCODE_EncodeFrameAsync() to be valid until
MFXVideoCORE_SyncOperation().

The b_frame_strategy option is only used by mpegvideoenc, qsv, x264, and
xavs, while b_sensitivity is only used by mpegvideoenc.
These are very codec-specific options, so deprecate the global variants.
Set proper limits to the maximum allowed values.
