Add tests for Ensure Docblock presence for wpm_apply_filters_typed() rule

[Miraeld]

As we were having trouble with the test implementation within this parent issue, we've took the decision to seperate the test implementation to the feature implementation.

The goal of this rule is to detect the type of param given from a docblock and check if the one used in wpm_apply_filters_typed() is the same.
Also, it makes sure we are having docblock for the mentioned function.
