Add a display list op to clear to transformation stack. (#32050)
This allows for the implementation of the
DisplayListCanvasRecoder::didSetM44. Instead of another operation that
clears the transformation stack along with setting a new transformation
on it. A single no-payload operation that clears the stack is added.
Existing ops to push to the stack are then reused.
