feat: add custom sleep timer picker (#2206)

## Summary

* **What is the goal of this PR?**
Mainly fixes #2196, but also allows users to set a sleep time of 1~30
min or to never sleep.

* **What changes are included?**

1. Revert changes from #1948 and #2137 (Sorry @Uri-Tauber)
2. Cherrypick changes from
https://github.com/uxjulia/CrossInk/commit/0cb91c3dd1c63f0559d4392fadc4a8340af5bdde
and
https://github.com/uxjulia/CrossInk/commit/4e6bd634b6ede51ff1a7107ba3e8efcd152bc6ee
for a timeout interval picker UI, the custom sleep time feature, and
migrate the existing setting in v1.3.0, `sleepTimeout`, to
`sleepTimeoutMinutes` (Thanks! @uxjulia)
3. Add a "Never" at the far right of the timeout interval picker
