In/NotIn operations for generated type predicates

The operations in entql/types.go include some operations but are missing others. Specifically they are missing the "In", "NotIn", "Contains", "NotContains" and other similar operators.

• I have searched the issues of this repository and believe that this is not a duplicate.

Summary

Can we add support for the missing operators? It would make building out privacy rules a bit more convenient.

Motivation

For example, when building the Query Rule to limit a request to only tenants the user has access to we have to do something like:

tenants := context.Tenants(ctx)
tenantsAny := util.Map(tenants, func(t int) any {
	return t
})

f.Where(entql.FieldIn(tenant.FieldID, tenantsAny...))

It would be nice if instead we were able to do this:

tenants := context.Tenants(ctx)

// This is assuming I have cast f with the WhereID(entql.IntP) predicate
f.WhereID(entql.IntIn(tenantsAny...))

Thank you! I would love to implement this if you would like!
