FIX: WIP Set macOS Xbox gamepad based on PID/VID

[jfreire-unity]

Description

An attempt to fix https://jira.unity3d.com/browse/ISXB-1264 in case @ieuanrees validates that this button mapping works.

Only for macOS since Windows uses XInput.
So far it only does this for a particular PID VID group and can likely be expanded and improved.

Ideally we could probably expand the coverage by using this database and define the layouts accordingly for Xbox controllers.

Testing status & QA

Overall Product Risks

Unclear what other combinations of PID/VID we are missing.

• Complexity: Minimal
• Halo Effect: Low

Comments to reviewers

In general, I don't like this approach since I'm creating a lot of duplication.
But if this solves the original bug while introducing regressions, I'm open to discuss a better approach with the team (after holidays)
