Add filter rules to phpunit.xml.dist to exclude *.api.php files

This issue is being reviewed by the kind folks in Slack, #needs-review-queue-initiative. We are working to keep the size of Needs Review queue [2700+ issues] to around 400 (1 month or less), following Review a patch or merge request → as a guide.

Not sure I see the "why" this should be done.
Could you elaborate more

- What is the purpose of the test coverage report?
- It is intended to help identify areas of the system that have not been adequately tested, and to provide guidance on which tests should be conducted next.

Not everything has to be covered with Unit or Kernel tests.
Maybe a certain part of the code is covered with FunctionalJavascript test, but for that is very difficult to get coverage report.
It is also true if a file is 100% green, it doesn't mean that it is covered with right and meaningful tests.

Do we need to write test to cover the functions in any *.api.php files?
Can we write test to cover the functions in any *.api.php files?

If the answer is "no", then why are those files in the coverage report?
