plugins: simplify VA video meta to only reference surface proxies.

Browse source 
Simplify GstVaapiVideoMeta to only hold a surface proxy, which is
now allocated from a surface pool. This also means that the local
reference to the VA surface is also gone, as it could be extracted
from the associated surface proxy.
