[Role Logic Move] Call Role/PackageManager with UserContext

This change ensures we call all user-dependent RoleManager and
PackageManager methods with a user context. This includes:

- packageManager.queryIntentActivities(...)
- packageManager.replacePreferredActivity(...)
- packageManager.getWhitelistedRestrictedPermissions(...)
- packageManager.addWhitelistedRestrictedPermission(...)
- roleManager.getHeldRolesFromController(...)

Also, lift UserHandle out of PreferredActivity::configure[AsUser] and
into a method argument.
