add support for syntax added with compiler 4.0

What does this MR do?

This adds support for new syntax added to compiler 4.0 and adds support for base 3.0.

I tested using this program:

module test

import syntax

import Clean.PrettyPrint.Common
import Clean.PrettyPrint.Expression
import Clean.PrettyPrint.Util

Start = print zero import1

import1 =
    { import_module = ident "Data.GenEq"
	, import_symbols = ImportSymbolsOnly [impDecl]
	, import_file_position = NoPos
	, import_qualified = NotQualified
	}

impDecl = ID_GenericCase (ident "gEq") [!ident "OBJECT", ident "CONS"!]

ident n = {id_name = n, id_info = {pointer = NilPtrN}}

The output is from Data.GenEq import derive gEq OBJECT CONS and I verified that this is accepted by the compiler as input.

Using ID_GenericDeriveClass gives from Data.GenEq import derive class gEq OBJECT CONS.

Changes to public APIs

Author's checklist (required)

• If bugs have been solved, tests have been added (guidelines)
• A changelog entry has been added (guidelines)
• Newly added code is documented (guidelines)
• Newly added code has a style consistent with the rest of the repository
• Intermediate commits compile (use git rebase -i main if not)
