Reset enforceNavigationBarContrast to system default value from API 31

so the splash screen theme won't corrupt activity's theme.
From API 31+, the splash screen isn't create as PhoneWindow, so it's
unnecessary to inherit the value from API 29.
Also remove the the override action from applyAppSystemUiTheme, since
enforceNavigationBarContrast could already changed from app side during
launch, override it from attribute doesn't make sense.

Bug: 330917018
Test: launch test app which never set enforceNavigationBarContrast in
postSplashScreenTheme, verify the value should stay in default unless
app has change it.
