Use <chrono> for input-related timeouts

There is a lot of confusion in input tests about the units used for the
timeouts. In a lot of cases, the timeouts are set too short, which
causes failures when they start getting enforced. To avoid this, use
std::chrono::duration for the timeouts.

Ideally, we should convert InputWindowInfo and InputApplicationInfo to
use std::chrono::nanoseconds, but that would be a larger change reserved
for a future release.
