hwc: vd: Add support for Dynamic Resolution Change (DRC)
1. Add support for Dynamic Resolution Change
We add support for DRC on virtual displays. This is achieved
by reading the width and height attributes that are set as
part of the buffer handle metadata.
For the WFD use cases, the WFD MultiMedia framework will
update the width and height during DRC by using setMetaData
API with UPDATE_BUFFER_GEOMETRY. We then proceed to configure
WB with the new resolution for subsequent frames.
2. Update WB dump with output buffer format and resolution
Update WB dump with output buffer format and resolution. This is
helpful for debugging purposes.
