fix: function type generation for zero arg and scalar computed fields

[7ttp]

Problems

1. Zero arg functions cause columns with same name to be omitted from query types (never extends T is always true)
2. Scalar computed fields like name_translated(products) are not added to Row types

Solution

1. Use Record<PropertyKey, never> instead of never for zero-arg function Args
2. Include functions with single unnamed table/view parameters in filtering logic

Suggested change

	const typesById = new Map<number, (typeof types)[number]>()
	// group types by id for quicker lookup
	const typesById = new Map<number, (typeof types)[number]>()

I think this should already be covered by: https://github.com/supabase/postgres-meta/pull/1035/changes#diff-c903ec71df16a8ae5f665c19c21b273f74c2f8eb02f5e8a3552ebe69d18be18fR196-R198 🤔

This needs to be tested with the inference within https://github.com/supabase/supabase-js/tree/master/packages/core/postgrest-js as I expect this might break a few things.

I remember having to use never specifically here to be able to detect the difference between actual functions with args, and functions with no args. Using a Record<string, never> in my memory didn't allowed that.
