#30092: Improve the default setting of 'show_in_admin_bar'

 Currently, the default setting of `show_in_admin_bar` is defined as `true
 === $args->show_in_menu`.

 Suppose, I have the custom post types CPT_A and CPT_B, and I put the menu
 of the latter one below the menu of the former one (`'show_in_menu' =>
 'edit.php?post_type=cpt_a'`).
 Unless I also define `'show_in_admin_bar' => true`, for CPT_B there won't
 be any _Edit post_ node in the admin bar.

 This is, in my opinion, not the desired behavior.
 If the default value for `show_in_admin_bar` were to be set with respect
 to the presence of `show_in_menu` - and not by strict comparison with it -
 the admin bar node in question would be made available automagically.

 Diff is attached.
