Add Mac OS tracy info to profiling docs

[mweatherley]

Explanation

I got kind of lost on this earlier (the Tracy docs are not very helpful) and required some assistance, so I thought it might be helpful to add this somewhere in the profiling docs. The way it's presently inserted is kind of awkward, but I don't know enough about the other operating systems to make similar sections for them, which I think would be helpful, since it's going to be different on each one.

Looks good, though this should be moved to the Contributor's Guide once that is more finished. :)

@mweatherley I'll merge this once the merge conflicts and linting errors are resolved.

Yeah, the issue is just that it has to be redone completely, since the current formatting can't actually be done in markdown without inline HTML. I can try rewriting the section in a way that incorporates it, I guess.
