encoders: add quality level tuning
This patch adds the handling of VAEncMiscParameterTypeQualityLevel,
in gstreamer-vaapi encoders:
The encoding quality could be set through this structure, if the
implementation supports multiple quality levels. The quality level set
through this structure is persistent over the entire coded sequence, or
until a new structure is being sent. The quality level range can be queried
through the VAConfigAttribEncQualityRange attribute. A lower value means
higher quality, and a value of 1 represents the highest quality. The quality
level setting is used as a trade-off between quality and speed/power
consumption, with higher quality corresponds to lower speed and higher power
consumption.
The quality level is set by the element's parameter "quality-level" with a
hard-coded range of 1 to 8.
Later, when the encoder is configured in run time, just before start
processing, the quality level is scaled to the codec range. If
VAConfigAttribEncQualityRange is not available in the used VA backend, then
the quality level is set to zero, which means "disabled".
All the available codecs now process this parameter if it is available.

encoders: add quality level tuning
This patch adds the handling of VAEncMiscParameterTypeQualityLevel,
in gstreamer-vaapi encoders:
The encoding quality could be set through this structure, if the
implementation supports multiple quality levels. The quality level set
through this structure is persistent over the entire coded sequence, or
until a new structure is being sent. The quality level range can be queried
through the VAConfigAttribEncQualityRange attribute. A lower value means
higher quality, and a value of 1 represents the highest quality. The quality
level setting is used as a trade-off between quality and speed/power
consumption, with higher quality corresponds to lower speed and higher power
consumption.
The quality level is set by the element's parameter "quality-level" with a
hard-coded range of 1 to 8.
Later, when the encoder is configured in run time, just before start
processing, the quality level is scaled to the codec range. If
VAConfigAttribEncQualityRange is not available in the used VA backend, then
the quality level is set to zero, which means "disabled".
All the available codecs now process this parameter if it is available.
