installer: add arm64 artifact option

[dennisameling]

Adds ARM64 support to the installer 🚀

Currently installs ARM64 Git into C:\Program Files (x86)\Git by default.

Great progress!

There is one more concern that I forgot to mention earlier: if we try to include artifacts from a directory outside of the pseudo root, the given approach won't work.

It would probably make more sense to imitate the $include_pdbs approach (but you don't need to copy, you just need to set the Source: attribute to the actual (Windows) path).

I admit that the sed call in the $include_pdbs clause is not for the faint of heart ;-)

Alright, just applied your suggestions! I did go with copying the files though; don't know how to convert the Unix-based /arm64 path to the Windows path in this case 😊

After installation, everything looks good:

Getting there! ;-)

Thanks! Just applied your suggestions @dscho. Tested and just had to apply a very minimal change to the sed command. Works now without copying the files first. Didn't know you can use cygpath to convert a Unix to a Windows path; learning something new every day 😊

Great!
