Adding arm64 support

[bkervaski]

Currently when building on Windows 11 arm, candle fails on the arch:

candle.exe : error CNDL0264 : The parameter 'arch' is missing or has an invalid value arm64. Possible values are x86, x64, or ia64.

With the inevitable shift to arm64 (Apple, Microsoft, AWS) we're adding arm64 builds to everything.

Any efforts to add arm64 targets for msi packages?

In lastest version, it works.
electron-wix-msi 5.1.3, light.exe (3.14.1.8722) and candle.exe (3.14.1.8722)
legal options for 'arch': 'msil', 'x86', 'x64', 'arm', 'arm64', or 'ia64'.

It doesn't seem explicitly supported if it is indeed working.

Their type signatures still exclude "arm64" as a supported type, and couldn't find anything in the commit history that mentioned "arm64" or indicated that it's now supported.
