Update build.yml to re-enable Windows on ARM64 MSVC build

[mcuee]

Previously there is an issue that CMake will pick up the wrong Python installation for the Windows ARM64 build. The issue is now gone. So we can re-enable Windows on ARM64 MSVC build.

Previous issue was found during testing of PR #1714.

• SWIG Python wrapper for libavrdude #1714

Now it is okay.

-- Found SWIG: C:/ProgramData/chocolatey/bin/swig.exe (found suitable version "4.1.1", minimum required is "4.0") found components: python
-- Could NOT find Python3 (missing: Python3_EXECUTABLE Interpreter) (found version "3.12.4")
    Reason given by package: 
        Interpreter: Wrong architecture for the interpreter "C:/hostedtoolcache/windows/Python/3.9.13/x64/python.exe"

@ndim @stefanrueger @MCUdude and @dl8dtl

Further enhancement is to install Python 3 for Windows on ARM64.

But I think we can leave that post 8.0 release.

Any objections?

@stefanrueger

This should be safe to be merged.

@ndim

I see that you have this change in #1888 as well. But I am not so sure if PR #1888 can be ready for 8.0 release.

• CI: test running the built avrdude executable #1888

I am sure #1888 will not be ready for 8.0 release.

@mcuee I will gladly rebase #1888 on top of whatever you have already made to work.
