Rewrite generated file checker tests
Summary:
This splits up the generated file checker tests into 3, uses `.arcunit`
to specify includes when they should be triggered, uses a base class for the
shared code and cleans up some of the bazel querying to figure out targets.
Test Plan:
Made changes that should trigger the unit tests. Ran `arc unit`
Before running generate scripts:
{F132932}
After running generate scripts:
{F132933}
