Unwrap FieldType Before instanceof chck

[bzhangam]

Is your feature request related to a problem? Please describe

Recently we have introduced FilterFieldType to core to support wrapping a delegate field type. But in core we have some logic which will check the instance of the FieldType so we should unwrap the field type before the check to ensure it's checking the right field type.

Describe the solution you'd like

Find all the instaneof check of the FieldType and unwrap the FieldType before the check.

Additional context

This is needed to ensure SemanticFieldType can work properly since it will extend the FilterFieldType to wrap a delegate FieldType.
