Launcher3QuickStepGo should have one Default Activity

Since Launcher3QuickStepGo including quickstep/AndroidManifest-launcher.xml
manifest in LauncherGoResLib adding additional default activity
launcher3.uioverrides.QuickstepLauncher along with launcher3.Launcher3QuickStepGo.
Since we have two default activity, intent resolver trying to resolve the
action and showing popup to  select home app.

This change add quickstep/AndroidManifest.xml for LauncherGoResLib which
does not have any default activity.

Bug: 288363376
Test: With this change we are not observing popup to select the home app.
