Increase test timeouts (Cherry pick of #18627, #18712, #18847, #18857) (

#18859)

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.
