This is partially an emergency fix also for https://invent.kde.org/plasma/plasma-mobile/-/issues/404, which was potentially introduced by https://invent.kde.org/plasma/plasma-mobile/-/merge_requests/582 This MR extracts the screen brightness implementation from initialstart to a QML plugin, and also ports the action drawer brightness slider implementation to it. This avoids importing the powerdevil screen brightness plugin on the lockscreen, which apparently has a race condition that causes it to sometimes segfault.
