Fix side button visibility tracking.

Previously one could e.g. get legacy menu button being visible in
certain scenarios, like this one:
- Open legacy app, e.g. CatLog
- Invoke IME
- Lock screen
- Unlock screen
- Result: Menu button visible in keyguard

SysUI: Fix QS tiles cutting off in the ribbon

Change I6dbe2d165398a8142e024db827208dc778003431 introduced a bug
where some Tiles would be cropped when certain themes are applied.

This patch resolves that issue.  Also moved the new dimensions to
cm_dimens.xml instead of dimens.xml.
