Víctor Manuel Jáquez Leal ffa2522fc0 va: Add GstVaSurfaceCopy class.
This new class is a helper for fast/tricky copy of surfaces. First it
tries to copy using the function vaCopy in libva 1.12. If it fails, or
it's not available, a GstVaFilter is tried to be instantiated with the
allocator's parameters, and if succeed, it's used for copying the
source surface.

This is required for dmabuf surfaces with drm modifier.
