[Autofill Assistant] Disable the carousels measurement cache.

Before this CL, when a carousel was pushed outside of the view port and
then brought back, it would not recompute its size and would be
invisible.

This CL invalidates the measurement cache of the carousels layout
manager to work around that bug.

After this CL, the carousel is correctly shown when brought back into
the view port.
