[SB][Chips] Squish 2 chips even when ChipsModernization is on.

Ideally we could do this in Compose and do it smartly (e.g. if we can fit the
first chip with text and the second chip as icon-only we should do that), but
given our time constraints, let's not worry about doing it in Compose for now.

Test: enable chips_modernization and then trigger 2 timer chips (e.g. call &
screen record) -> verify both chips show and show as icon only
