This applies the "whitelist" => "include" changes to all the core
phpunit_coverage_info occurrences, so core won't emit any deprecation
warning (see previous commit).
At the same time, modified a bunch of comments in coverage files
to be more readable/understandable.
The current ->setMethods() has been silently (won't emit any
warning) in PHPUnit 9. And will stop working (current plans)
in PHPUnit 10.
Basically the now deprecated method has been split into:
- onlyMethods(): To point to existing methods in the mocked artifact.
- addMethods(): To point to non existing (yet) methods in the mocked
artifact.
In practice that means that all our current setMethods() calls can be
converted to onlyMethods() (existing) and done. The addMethods() is
mostly useful on development phases, not final testing.
Finally note that <null> isn't accepted anymore as parameter to
double all the methods. Instead empty array [] must be used.

With stricter typed param checks in php73, the 7th param of the
getMockForAbstractClass() must be array, so previous code defaulting
to null now throws a TypeError.
