Enable Metal Backend for UPBGE

[hezishah]

Hi. Currently when enabling Metal Backend on macOS, starting the game only draws one triangle.
Are there plans for enabling that?

Yes, i'm investigating how to fix it

Any updates?

Hi.
In latest upbge HEAD, I had to do a compile fix in
upbge-compile-fix.patch
and a runtime fix to prevent runtime crash.

upbge-runtime-fix.patch

After those fixes, the Game Engine would run, however only ViewPort Rendering works.

Will we have UPBGE standalone render work in the coming future for M1/2/3 Macs?

Thanks for the fixes. In august I will have some free time to try fixing MacOS port.
