Mixed Reality Toolkit

NOTE: 2.5.2 contains a build regression for Oculus. Please use 2.5.3 instead.

In the core layer, Mixed Reality Toolkit 2.5.2 is a minor update that addresses some issues that impact importing via the Unity Package Manager (UPM) on Mac. It also fixes a bug with boundary layers not showing up.

In the provider layer, it adds preview support for HoloLens 2 and Windows Mixed Reality immersive headsets on OpenXR.
