Provide wheel for Windows ARM64

[khmyznikov]

What is the current behavior?

Unable to install the package from pip.

What is the desired behavior?

To have native wheel for WoA. GitHub Actions now supports win-arm64 for free.

How would this improve sentencepiece?

Due to the library's popularity, a native version for the growing number of Windows on ARM (WoA) devices offers a better user experience
