 base/TimerManager: Clamp timer expiration time to maxBound

 Previously we would allow the expiration time to overflow, which in
 practice meant that `threadDelay maxBound` we return far earlier than
 circa 2500 CE. For now we fix this by simply clamping to maxBound.

 Fixes #15158.

 Test Plan: Validate, run T8089
