Add support for Mac (macOS)

[aaronfranke]

I'm opening this issue to track the status of Mac (macOS) support in NeoAxis. This comes in 2 main parts:

• [ ] macOS support for exported games
• [ ] macOS support for the editor

After basic macOS support is in NeoAxis, there is also the matter of porting the engine for Apple Silicon (ARM64) platforms.

• [ ] Apple Silicon support for the editor
