Show METAL_CAPTURE_ENABLED in Metal.versioninfo() when the environment variable is set

Good idea, thanks!

Also, since you're apparently profiling Julia/Metal.jl code: It would be great if the profiling docs could be extended a little, e.g., on how to actually use Xcode (maybe with some screenshots like the CUDA docs). If you have the time, of course. I personally don't have much experience with Xcode, so would probably learn a thing of two from it too 🙂

To be completely honest I was just using the profiling to see if any obvious differences between MacOS 13 and 14 showed up that would explain why things crash and I noticed the environment variable didn't show up in versioninfo. I have probably used Xcode as much as you have.

Oh yeah Sonoma is unsupported: #201
The problem seems to be that the LLVM IR AIR emitted/consumed by macOS 14's toolchain has some additional metadata, which I haven't figured out yet. I asked Apple, but didn't hear back, and I haven't had the time yet to reverse engineer the changes.
