gh-110088, gh-109878: Fix test_asyncio timeouts

[vstinner]

Fix test_asyncio timeouts: don't measure the maximum duration, a test should not measure a CI performance. Only measure the minimum duration when a task has a timeout or delay. Add CLOCK_RES to test_asyncio.utils.

• Issue: test_asyncio.test_windows_events: test_wait_for_handle() failed on GHA Windows x86 #110088

Windows x64 failed with:
