Use the packaging script for the github action

Unifies a bit of what is done. For example this adds documentation and creates a disk image for
macOS. It will also make adding perfparser/elfutils and 32bit wininterrupt and qtcreatorcdbext
easier.

Adds Qt translations.
Adds some useful options to build.py and make it work with python3
Disables detection of debug vs release build in deployqt.py on Windows
if dumpbin is not there (for MinGW).
