When building legacy shortcut, Launcher calls PackageManager#resolveActivity to retrieve necessary permission to launch the intent. However, when the source app wraps an arbitrary intent within Intent#createChooser, the existing logic will fail because launching Chooser doesn't require additional permission. This CL fixes the security vulnerability by performing the permission check against the intent that is wrapped within.

Intent created for Chooser should not be allowed in legacy shortcuts since it doesn't make sense for user to tap on a shortcut in homescreen to share, the expected share flow started from ShareSheet.

Fix permission issue in legacy shortcut

However, when the source app wraps an arbitrary intent within Intent#createChooser, the existing logic will fail because launching Chooser doesn't require additional permission.
