plugins: direct rendering on memory:VASurface

Browse source 
As buffers negotiated with memory:VASurface caps feature can also be
mapped, they can also be configured to use VA derived images, in other
words "direct rendering".

Also, because of the changes in dmabuf allocator as default allocator,
the code for configuring the direct rendering was not clear.

This patch cleans up the code and enables direct rendering when the
environment variable GST_VAAPI_ENABLE_DIRECT_RENDERING is defined,
even then the memory:VASurface cap feature is negotiated.
