Deprecate setMethods()

[mondrake]

Q	A
PHPUnit version	9.5
PHP version	n/a
Installation Method	n/a

Summary

Working on adjusting Drupal for PHPUnit 10, I realized MockBuilder::setMethods is removed from PHPUnit 10. Unlike other methods deprecated in PHPUnit 8 and 9, there's no warning thrown about the deprecation.

Since in Drupal we rely on deprecation errors being triggered, so far this deprecation was missed from any conversion.

Current behavior

n/a

How to reproduce

n/a

Expected behavior

I suppose a Warning should be thrown in PHPUnit 9, on top of the annotated deprecation.

Unfortunately, "soft deprecation" (annotating the methods in question with @deprecated is the only feasible way to do this.
