WIP: Windows on Arm support

[archanox]

PR Details

This is a highly experimental WIP draft of getting the entire Stride suite to compile and run on Windows on Arm (WoA).
There has been a lot of broad stroke changes that change projects from win-x64 to win-arm64, just to test this proof of concept.
I have gone through every mention of x86/x64 through the repo to add in arm64 where appropriate, but there are some issues surrounding the native libraries. I feel that there's perhaps documentation somewhere on how to build these binaries that exist in the repo, maybe?

I am seeking any and all feedback and assistance with this PR where possible. I am on Discord in the Stride server as pierce @archanox

Milestone:

1. Getting the solution to build for arm64 with everything working (tests, packaged, installer built, etc)
2. Configure multiple targets for a win-x64 build and win-arm64

Current Issues checked in:

• ClearScript was only bundled with x86/x64 binaries. Dependencies for the Metrics were erroneously upgraded for the entire project. Untested.
• There are missing binaries for arm64 that do not exist in the repo
• 32bit/64bit checks assume x86 platform
• Native library build scripts appear to be pointing at an old version of visual studio
• MSBuild paths for x86/x64 have been temporarily removed until successful build & test.
• Preliminary ARM64 UWP changes were checked in, but will likely be reverted.

Goal of this PR:

• To develop on a WoA device, with Visual Studio integration and to build for Windows and Linux platforms.

Outside the scope of this PR:

• CI for automated builds of the arm64 version
• NuGet publishing

Was there any more movement on this (or discussion on other platforms)? Was there anything preventing review?

Hi Anthony, no movement I'm afraid. I've been pretty intimidated by Stride's bespoke build system.
At the time of me authoring this PR, there was still a lot of native dependencies that are precompiled and checked into the repo.

The last thing I believe I got stuck on was actually building the dependencies and locating where they need to live. MSBuild wasn't very transparent to what the cause was, merely just reporting what broke because of it.

As for review, if anyone else is interested in this PR, I'd advise just spinning up a new one without the mess I made when making the entire solution build and run just for aarch64 rather than x64.

If you are interested in picking this up and wish to avoid reading the mess in the singular commit, I think the main take aways are that

• the MSBuild location in the registry is in another location.
• The version of MSBuild that Stride targeted when I looked last was a version prior to a native WoA version of it.
• And the Url referenced to download MSBuild for arm64 is actually a fat binary for both x64 and arm64.
