SiteConfigureForm can install the file module without the field module

Problem/Motivation

Many moons ago we made the field module not required. This subtlety broke an assumption made by \Drupal\Core\Installer\Form\SiteConfigureForm. It does
$this->moduleInstaller->install(['file', 'update'], FALSE); under the impression that all of these modules dependencies are required. This is no longer true.

So if you install the testing profile via Drush core.extension:module looks like:

module:
 dynamic_page_cache: 0
 file: 0
 page_cache: 0
 system: 0
 update: 0
 user: 0
 testing: 1000

Proposed resolution

Add field to the list of modules to install.

Remaining tasks

User interface changes

API changes

Data model changes
