Let tests mock the list of feature flags (#169140)
This moves the tool's `allFeatures` global to
`FeatureFlags.allFeatures`.

In the future, this will be used by tests to mock the list of feature
flags and replace them with test flags in various states. See:
https://github.com/flutter/flutter/pull/168437

Flutter reports data to two separate systems:

  1. Anonymous usage statistics are reported to Google Analytics (for statistics such as the number of times the flutter tool was run within a given time period). The code that manages this is in [usage.dart].
  2. Crash reports for the flutter tool. These are not reports of when Flutter applications crash, but rather when the command-line flutter tool itself crashes. The code that manages this is in [crash_reporting.dart].

Opting out

Users can opt out of all reporting in a single place by running flutter config --no-analytics.
