Make different type aliases compaitble in diff, intersect and merge

[error17191]

Description

Make it works when calling diff, intersect or merge on two collections having the same type but with different aliases like int and integer

This applies on:
int, integer
bool, boolean
float, double

Motivation and context

Code like this should work without having to construct both collections as int or integer

(new Collection('integer', [1, 2, 3]))->diff(new Collection('int', [1, 2]));

How has this been tested?

I added a method to test it in CollectionManipulationTest
