Tests: Explicitly mark empty REST API tests as not performing any assertions.

WordPress core test suite uses PHPUnit's `beStrictAboutTestsThatDoNotTestAnything` option set to true, which marks a test as risky when no assertions are performed.

REST API test classes have some empty tests for non-implemented methods because these test classes extend the abstract `WP_Test_REST_Controller_Testcase` class, which requires several methods to be implemented that don't necessarily make sense for all REST API routes.

As these tests are intentionally empty, they were previously marked as skipped, so that they are not reported as risky.

This commit aims to further reduce noise in the test suite and effectively ignores these empty tests altogether, which seems like a more appropriate option at this time.

The `@doesNotPerformAssertions` annotation can be reconsidered in the future when the tests are either removed as unnecessary or updated to actually perform assertions related to their behavior.

Follow-up to [40534], [41176], [41228], [53921].

See #40538, #41463, #55652.
