The implementation doesn't share much with get.c because:
* the refactoring needed for get.c to not depend on ctx->Array.VAO would
be quite large
* glGetVertexArray* would still need to filter pname to only accept the one
specified by the spec
* these functions are getter, the implementation is trivial (the complexity
is in the correct filtering of pname input)
