Removing a few UNIMPLEMENTED cases

A few remaining cases in Context.cpp are actually implemented, so we can remove the UNIMPLEMENTED() calls in these cases: Primitive restart, uniform blocks, fragment inputs and vertex outputs are all implemented. Also, the implementation can legally support 0 program binary formats.
