This cherry-picks a bunch of test timeout increases from main to 2.16.x, to reduce the number of spurious re-attempts required for other cherry-picks.
Fully cherry-picked: #18847, #18857
Partially cherry-picked (just the timeout increases): #18627, #18712.
Motivation: when cherry-picking, #18832 required 8 re-attempts, #18839 required 5 and #18850 got to 13, almost all due to tests timing out. Various other cherry-picks likely required many re-attempts too.
