Currently the lockscreen takes 5 seconds to load for me on the OnePlus 6. This MR moves the quicksettings and status bar to only load once the initial lockscreen has loaded (to avoid blocking it). This brings it down the initial load to 1 second for me.
Brought the over-scroll effect found in the pinned quick settings panel to all the portrait mode quick settings states.
This helps improve the user experience while also bringing more consistency when pulling down the panel.

This (partially) reverts commit 127bbdf653.
Only incorrect changes from Kirigami.Units.largeSpacing to
Kirigami.Units.gridUnit are reverted. Only Plasma.Units were buggy.
Search and replace all the occurrences of Svg/FrameSvgItem/SvgItem
to their new implementation from KSvg.
Changes only namespace, API is the same

Having a global set margins and orientation (that were calculated from the panel containment) caused a lot of issues with the way bindings were evaluated across panels, and with high coupling.
Now use properties from within containments to determine shell margins instead, which removes the dependency on other containments for measurements. This allows us to get rid of TaskPanelControls as well!

Hi, this MR adds "clear all" and "do not disturb" buttons to `NotificationsWidget`.
Few other corrections have been made:
- Transitions should now work correctly, plus they can be disabled via `MobileShell.MobileShellSettings.animationsEnabled`;
- Loaders are now asynchronous;
- List items have now their own margins, in order to not clip their shadows.\
It only remains to implement a context menu to set do not disturb mode for a given period of time. I think it's a secondary feature on which we can work later, but in case tell me what to do.
Unfortunately I can't test the lockscreen on a phone at the moment, and I cannot take a performance test as well. It would be great if someone tested all these things, otherwise I'll provide as soon as possible.
