JavaFX Metal: First EA build available for Testing

[Christopher Schnick]

I tested this build with our application on macOS 15.2 ARM and it worked 
perfectly fine. There were a few small color differences looking at it, 
but I see in the tracker that is already a known issue. Our application 
doesn't use any advanced rendering features where performance is 
critical, so I can't say anything about the performance difference. For 
the normal basic user interface, it felt the same as before.
