Build with `--enable-profiler`

[bitbloxhub]

Motivations

I have a rust sever and embedded project in the same repo, and I would like to get code coverage from the server.

Solution

Build rust with --enable-profiler

Alternatives

Figure out how to use a different rustc for my server and embedded.

Additional context

Sorry, I forgot to do this for 1.94 builds. I'll make the changes in rust-build now, so that its ready for 1.95.

I ended up doing a 1.94.0.1 and 1.94.0.2, the latter contains the profiler.
