Include support for Windows on Arm on BUILD.bazel along with proper Volterra detection

[everton1984]

This MR includes support for building with Bazel on cpu arm64_windows, I also tried this on my Volterra Windows Dev Kit and noticed that the core string seems different from what the current source code defines. I don't know if this is because my hardware is a bit different or not.

I ran the tests with the following results

@malfet , @everton1984 ;

First of all, thanks for the contribution.

However, we are considering that this PR is causing an issue for detection Ampere(R) Altra(R) Processor.

Thus, we created an issue with the details and a possible solution with PR.
