Possibility to add class method as a sanitized function

[9brada6]

Is your feature request related to a problem?

✔ If I try to add a function that sanitize my input -> works, without a question.
❌ If I try to add a static method or just a simple class method -> it will not work(Maybe there is a possibility, but I can't find an example).

Describe the solution you'd like

Possibility to add in config class methods to sanitize inputs, something like:

<rule ref="WordPress.Security.ValidatedSanitizedInput">
    <properties>
        <property name="customUnslashingSanitizingFunctions" type="array">
            <element value="sanitize_field"/><!-- This works, other 3 don't -->
            <element value="MY_Custom_Class::sanitize_field"/>
            <element value="MY_Custom_Class->sanitize_field"/>
            <element value="array(MY_Custom_Class, sanitize_field)"/>
        </property>
    </properties>
</rule>

<rule ref="WordPress.Security.NonceVerification">
    <properties>
        <property name="customUnslashingSanitizingFunctions" type="array">
            <element value="sanitize_field"/><!-- This works, other 3 don't -->
            <element value="MY_Custom_Class::sanitize_field"/>
            <element value="MY_Custom_Class->sanitize_field"/>
            <element value="array(MY_Custom_Class, sanitize_field)"/>
        </property>
    </properties>
</rule>
