[stable-2.19] 🧪 Set timeouts for CI jobs (#86108)

Sometimes, AZP would mark steps in jobs as cancelled when they've
actually exited successfully but on the boundary of the default
60-minute timeout. Such logs might be difficult to reason about.

Additionally, `entry-point.sh` sets a 60-minute timeout for the main
test invocation but it would never trigger earlier that AZP would kill
such a job as the job-global timeout was 60 minutes already and it'd
always be hit earlier than the test runner one.

The patch sets maximum observable job timeouts with extra buffer to
account for flakiness.
