T194585 raises a use case for callers to be able to know why an action
is not allowed. We can make that possible easily enough. The default
remains to return only a boolean.
This also deprecates inprop=readable in favor of intestactions=read,
since they both just return `$title->userCan( 'read', $user )`.
