Handle uiMode changes in QuickstepLauncher

- Added uiMode in handled configChanges for QuickstepLauncher, NexusLauncherActivity and RecentsActivity
- This avoids Launcher from being recreated when swithching from an app in driving mode (e.g. Maps), which causes massive jank
- Launcher layout is affected when driving mode changes, so a recreation is ujnnecessary
- Light/dark mode changes still causes Launcher to create as expected

Fix: 339747262
Test: Swtich from driving mode app to another or home in 1p and 3p laucnher
Test: Switch light/dark mode and Launcher is updated correctly
Flag: EXEMPT bugfix
