feat: add multiple getters mode in generate_getter

[feniljain]

This commit adds two modes to generate_getter action.
First, the plain old working on single fields.
Second, working on a selected range of fields.

Should partially solve #13246
If this gets approved will create a separate PR for setters version of the same

Points to help in review:

• generate_getter_from_record_info contains code which is mostly taken from assist before refactor
• Same goes for parse_record_fields
• There are changes in other assists, as one of the methods in utils named find_struct_impl is changed, before it used to accept a single fn_name, now it takes a list of function names to check against. All old impls are updated to create a small list to pass their single element.

Assumptions:

• If any of the fields have an implementation, the action will quit.
