avutil/hwcontext: Allocate AVHWFramesCtx jointly with its internals

Browse Source 
This is possible because the lifetime of these structures coincide.
It has the advantage of allowing to remove AVHWFramesInternal
from the public header; given that AVHWFramesInternal.priv is no more,
most accesses to AVHWFramesInternal are no more; indeed, the only
field accessed of it outside of hwcontext.c is the internal frame pool,
making this commit very simple.
