Import link.xml into assets with Package

[rob1997]

Summary Currently for Unity v2021 or less we need link.xml to include certain namespace for a working IL2CPP build on IOS. We should streamline/automate that process on package imported.

Suggested features or ways to address the summary

• We should have an editor with [InitializeOnLoad] to load on package import (using constructor)
• Encase class in #if !UNITY_2022_1_OR_NEWER directive since this issue was fixed in v2022 and up
• Check if link.xml was imported using EditorPrefs if not import it

Motivation This decreases complexity and onboarding for DevEx.

Acceptance Criteria Importing link.xml should be streamlined and IOS build must work when package is imported from an empty project
