QS: remove MTK screen timeout tile
Presence of this tile is hard coded and it's hard to determine whether
it's included in ROM or not to dynamically update the list of tiles in
GB settings. Explicitly remove this tile by adding it to the MTK tile
map without possibility to control its visibility via GB's QS settings.
It's redundant to GB's screen timeout tile which is more flexible,
anyway.
QS: hide cast screen tile based on its remote callback policy
Hides tile only in case it was set to be visible only when enabled. This
e.g. follows MTK decission to have this tile always visible.
