Add GitHub actions workflow to build utils/makemhr on update (#783)

* Build utils/makemhr on update

This workflow builds makemhr.exe including dependencies (libmysofa, zlib, etc) whenever anything under utils/makemhr or the workflow is updated.
It also uploads artifacts and [(pre)releases it with its own tag](https://github.com/ThreeDeeJay/openal-soft/releases/tag/makemhr) for a [permanent, up-to-date download link](https://github.com/ThreeDeeJay/openal-soft/releases/download/makemhr/makemhr.zip).

* Clone latest libmysofa release tag without history
