If any recipes were previously applied, show them as checked and disabled in the installer

Problem/Motivation

#3496399: The installer should track which recipes it applies, in order to recover from timeouts and other interruptions added some fault-tolerance to the installer aimed at people who are trying to use Drupal CMS on underpowered, shared hosting platforms. The installer tracks which recipes it has successfully applied so that, if it should fail or time out in mid-stream, you can go back to the beginning and pick up where you left off.

Right now, any already-applied recipes are just silently skipped. But that can be a user experience problem if you don't remember which recipes you chose the first time around, and then you are met with unexpected things after the installer completes (these are things you opted into, of course - but if you don't remember choosing them, it might well be an unpleasant surprise).

Proposed resolution

If you are trying the install again after it failed partway through, the recipe selection form should give you some visual indicator that you already applied certain recipes. Maybe they are not presented as options at all, or maybe they are checked and cannot be unchecked (since they've already been applied anyway, you can't exactly undo them). I'm not sure what the best and least confusing thing would do. Let's figure out what user experience might be best, and implement that in the installer accordingly.
