ARM64 Windows support

I did a quick test on a test installation of Windows 10 for ARM64 on a Raspberry Pi 4 and found that it works.

To make it work, ensure the following has been done:

Install Windows Insider Preview - see https://insider.windows.com/en-us/ for instructions to sign up and configure Windows Update This is required since the retail version only supports whitelisted OpenGL applications on ARM64. Since Windows 11 has certain system requirements certain older devices might not be eligible to receive Windows Insider Preview Dev builds.
Install the OpenCL and OpenGL Compatibility Pack - https://www.microsoft.com/en-us/p/openc ... verviewtab - A Microsoft account is not required to download this from the Store however it is required to set up Windows Insider Preview.
If testing DXGL x64 build using the preview x64 emulation feature, make sure to download and install Visual C++ Redistributable first, as the installer may throw DLL errors when invoking DXGL during setup otherwise.

Please note in my tests DXGL was quite slow, but this is likely only because there are no hardware accelerated display drivers available for Windows 10 on Raspberry Pi 4.

These instructions should also work for the latest Windows 11 previews, and may work on Windows 11 retail too.
