Got to implementation for a record (field) should take me to the constructions of the record (field)

## Problem

A record type definition defines an interface. Often I am looking at this interface, and want to see implementations of it.

I can already use got to references to see places that the record or record field is used either as a selector or a constructor, but I want to just see places where we are constructing this specific record or field.

More concretely, this is something I want when looking at a Servant named API.
The API is defined as a record and I often want to jump to the code that defines the handler for that API.

## Describe the solution you'd like

When I hover over a record constructor and go to implementation, then I should see all the places a record is constructed.

When I hover over a record field and go to implementation, then I should see all the places that this field is being constructed. If RecordWildCards are being used then I should see where the variable is defined rather than `..`.

## Additional context

Start by examining the existing go-to-references behavior for record types and fields, using the Servant named API example as a concrete case. The work is done when go-to-implementation on a record constructor finds record constructions, and on a field finds its construction sites, including the defining variable when RecordWildCards are used.
