This is a retry/relanding of
https://chromium-review.googlesource.com/c/chromium/src/+/1269524.
We're having a *very* hard time reproducing the flakes that the trybots
experienced, but I've made some improvements to attempt to reduce
possible race conditions in the browsertests.

Patch set 1 is the original CL; patch set 2 contains the new changes.

(When a card accrues 3 strikes, future offers to save for that card
should show the omnibox save icon, but NOT pop up the bubble.
On Android, no offer to save is shown at all.)
