[Fix] (MG_Impl/GLImpl): unblock the non-texture sections of GL CTS per-case state reset - clamp advertised GL_MAX_UNIFORM_BUFFER_BINDINGS to the state layer indexed-binding capacity (glBindBufferBase rejected indices past it), let glBindRenderbuffer(0) unbind without recording INVALID_OPERATION (name 0 must never reach the name-table lookup), and allow writes to generic vertex attribute 0 current value (core GL has no attribute-0 restriction; gluStateReset writes vertexAttrib4f(0,...) after every case) - with these plus the default-texture work, multi-case glcts batches complete in one process instead of aborting after the first case
