Add recommended category for default app page

For assistant, it can be enabled by overlaying PermissionController
config_recommendedAssistants with a list of package names, optionally
with signing certificate digests if the app needs to be a non-system
app, similar to the config for default holders.

This is not available for the request role dialog yet and thus still
can't be used with a role that allows requesting.
