[Eideren]

PR Details

This PR is to fix the mobile builds according to Xen2.
Doesn't seem to work at the moment, Stride.Core.Assets.CompilerApp.dll throws the following when building a game:

Unhandled exception. System.TypeInitializationException: The type initializer for '<Module>' threw an exception.
 ---> System.IO.FileNotFoundException: Could not load file or assembly 'Stride.BepuPhysics, Version=4.3.0.1, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.
