Provide default splash screen style for Launcher and SystemUI.

Browse Source 
Previous the splash screen style can either be EMPTY or ICON, and need
to be set by new hidden API #setSplashscreenStyle, so the flag will
always be "EMPTY" for those 3rd party Launcher Apps which may have not
upgrade to targetSDK 31.
To correct the default behaivor for Launcher Apps, create a new
UNDEFINED style as default value for splashScreenStyle, and if the
value is UNDEFINED, determine the style by checking the launch source.

Test: Verify no change when default home is NexusLauncher.
Test: Set 3rd-party Launcher as default home, verify the splash screen
style should be ICON style when launch app from Launcher.
Test: atest SplashscreenTests
