add "is in list" search option for string/localestring attributes

We would like to have an option added, so you can search within a list of values - like the "contains any" for CVL attributes, but then for strings/locale strings or even numeric values. Under the "equals" dropdown, have the possibily to select "is in list".

Example use case = being able to search items with a specific GTIN. In other PIM tools I can easily add a list of values

Returning me as a result all the items with a GTIN containg a value from the list.
