python: Remove 'scheduleTickExit' in favor of 'exitSimLoop'

The commit https://gem5-review.googlesource.com/c/public/gem5/+/66231
added an API to m5 for scheduling to-tick exit events. This added the
function `schedule_tick_exit`. It was later pointed out that this
`schedule_tick_exit` event is redundant given the existance of
`exitSimLoop`. This patch therefore removes `schedule_tick_exit` in
favor of `exitSimLoop`.
