We so far have been recreating the background elements for all the item throughout the shell. This merge request simplifies this by unifying these elements into a single component, making is easier to keep things at a consistent design while also being able to adjust things when needed in the future.
Per request, I tried to keep thing looking mostly the same as before.
The first picture is what the action drawer looks like now, the one after is with these changes.


Currently opening the action drawer causes notification popups to
"expire", causing some unintended behaviour (ex. dismiss alarm/timer).
This commit removes this behaviour, and also fixes notification popup
expiry while the action drawer is open.

This merge request adjust animations in the VolumeOSD and NotificationPopup to bring consistency and to make it feel better when swiping up a notification.
This fixes a bug where other sources dismissing the current popup notification would cause notifications in waiting to be assigned to the popup index of -1. This would cause these remaining notifications height to get set to a very thin strip at the top of the screen and would no longer automatically dismiss. This also fixes a bug where notifications in the popup drawer would become bunched up together at the top.
