GsFExtrapolator : make all public methods and few internal to return unique_ptr
Following !27948 (merged)
For IMultiStateExtrapolator
/ GSFExtrapolator
make all interface/public methods return unique_ptr.
Actually the implementation of quite a few of them was doing a release
which can be avoided.
The release
now bubbles a bit to the caller side. One level at a time, but we are almost there.
