[FR] Add Windows Arm64 support

[loic-sharma]

Feature proposal

• Firebase Component: All

The FlutterFire package downloads a pre-built library. Currently it assumes an x64 architecture and fails on Windows Arm64 machine.

Ideally the Firebase C++ SDK would also publish a Windows Arm64 library. This would enable the FlutterFire package to choose the correct library based off the target architecture.

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Are there any updates?

The latest version 11.8.0 does not yet have Windows Arm64 pre-built libraries.

Also running into this. At link-time it complains about missing symbols due to architecture conflicts of it trying to use the x64 directory for the lib files.
