GstVaapiMiniObject and GstVaapiObject are deprecated.
This is the first step to remove them by porting GstVaapiCodedBuffer
as a GstMiniBuffer descendant.

MbCode, MV and Distortion buffers (fei codec objects)
can be treated as output of different fei modes based user request.
For eg: MbCode and MV are the output of ENC only. MbCode, MV and Dist
can be dumped as output in ENC_PAK mode for analysis purpose.
So treating them as a part of CodedBufferProxy too.
Here we avoided Qp, MbControl and MvPredictor codec objects since
there is no practical use case of treating them as "output buffers".

Refactor the GstVaapiCodedBuffer APIs so that to more clearly separate
public and private interfaces. Besides, the map/unmap APIs should not
be exposed as is but appropriate accessors should be provided instead.
* GstVaapiCodedBuffer: VA coded buffer abstraction
- gst_vaapi_coded_buffer_get_size(): get coded buffer size.
- gst_vaapi_coded_buffer_copy_into(): copy coded buffer into GstBuffer
* GstVaapiCodedBufferPool: pool of VA coded buffer objects
- gst_vaapi_coded_buffer_pool_new(): create a pool of coded buffers of
the specified max size, and bound to the supplied encoder
* GstVaapiCodedBufferProxy: pool-allocated VA coded buffer object proxy
- gst_vaapi_coded_buffer_proxy_new_from_pool(): create coded buf from pool
- gst_vaapi_coded_buffer_proxy_get_buffer(): get underlying coded buffer
- gst_vaapi_coded_buffer_proxy_get_buffer_size(): get coded buffer size
Rationale: more optimized transfer functions might be provided in the
future, thus rendering the map/unmap mechanism obsolete or sub-optimal.
