Subject: [PATCH] [Large screen] Disable/enable DeepLinkHomepageActivity

This change enable/disable DeepLinkHomepageActivity according to
SplitController#isSplitSupported when receiving PRE_BOOT_COMPLETED.

PRE_BOOT_COMPLETED is an Intent which broadcasts once when the user
is booting after a system update.

Bug: 201236463
Bug: 201237323
Test: manual
      1. On a large screen device, Launcher -> Wallpaper & style
         Observe it uses intent ACTION_SETTINGS_LARGE_SCREEN_DEEP_LINK.
      2. On a small screen device, Launcher -> Wallpaper & style
         Observe it does NOT use intent ACTION_SETTINGS_LARGE_SCREEN_DEEP_LINK.
