Add: add macos packaging, build for multiple games

[jmckisson]

This adds AppDmg creation for macOS.
I have also added for macOS and Windows building for multiple games listed in the GameList.txt, just a few for now.
It essentially modifies the ini file that specifies the game to launch and rebuilds for each.. Technically a rebuild isn't needed just some copying of files after building the first, but this is working for now and I'll optimize later.

Currently unable to test this on my personal Mac as it is still running macOS 12

I'll test this out on my mac! As a sidenote, try out dockur/macos. It doesn't run the quickest, but once you give it more than the default RAM / cores, it works "OK".

It runs! 🌟

Trivial issue, the icon is missing:

The actual download didn't work, I'm not sure if that is correct or not:

[jmckisson]

Ah hmm I'll investigate. I forgot I had it set to fetch PTB's which may be one issue but if it was listed in the feed but not a real download then it may be some other issue. I'll get the dockur thing up and running...

[jmckisson]

Not sure what's going on with the icon, the mudletbootstrap-appdmg.json points to the correct file...
I switched the download mode to release and it now properly grabs the latest 4.19 release, the previous PTB download doesn't actually exist despite being the top listing in the public-test-build feed.

Let's merge it for now? I'll start to add the signing.

Ah, yea that sounds good, I was waiting for the Windows build to complete it was taking forever because the qt build cache expired
