main: Added utility function _mesa_lookup_texture_err().
Most ARB_DIRECT_STATE_ACCESS functions take an object's ID and use it to look
up the object in its hash table. If the user passes a fake object ID (ie. a
non-generated name), the implementation should throw INVALID_OPERATION.
This is a convenience function for texture objects.
