Nika Layzell fc835b08d2 Bug 1781129 - Part 3: Remove Shmem overload of GetSurfaceData, r=edgar
After the previous changes there was only one consumer left of the Shmem
version of GetSurfaceData, which could easily be changed to use BigBuffer,
removing the need for that overload.

After that consumer is removed, the interface was also simplified as the
generic logic in the implementation was no longer necessary.
