RuleTestCase: error tagging to allow reusal of php templates

[janedbal]

The idea is that you have single code.php and you have multiple testcases slightly adjusting some params resulting in different errors reported. So you can do

generic error always reported // error: Missing native return typehint array
reported only when called with $this->analyseFile(..., ["php 8.2"]) // error (php 8.2): Missing native return typehint null

But it does not help when error on certain line change with some setup.

Not generic enough, closing.
