batu_hoang b422a65a00 Add retry for hit tests with expired epoch in result (#37085)
Follow up to [hit_test failed occasionally when the touch event is
sent](https://github.com/servo/servo/issues/35788#top) and
https://github.com/servo/servo/issues/36676#issuecomment-2882917136,
this PR adds a retry for hit tests with expired epoch in result.

Hit tests with outdated epoch mean it is too early to perform the hit
test.

Solution: retry hit test for the event on the next webrender frame.
The retry should guarantee that:

- Keep the correct order of events
- Retry time is not too long

Test cases: `./mach test-wpt --product servodriver -r
tests\wpt\tests\webdriver\tests\classic\element_click\events.py`
