Update clip with implicit function filter's field map

Browse Source 
MR !2969 was meant to update the clip filters such that their field
mapping works on any field type and preserves the value type. Although
this was done for `ClipWithField`, it was not fully implemented for
`ClipWithImplicitFunction`. These changes update
`ClipWithImplicitFunction` to match its sibling.
