Add gRPC export for profiles signal type.

Nothing much exciting in the code here, it's mostly to a pattern copied from other signal types. The code packaging differs a little, since the profiles signal is still in development and doesn't yet have a separate user API. This makes the dependencies for both the profiles module and the exporters testing-internal module a bit messier than I'd like, but it should get straightened out when things move out of development phase. Could perhaps be 'improved' at the cost of duplicating more of the test harness, but I'm not convinced that would count as a win.

Just a handful of minor comments. Thanks!

@jack-berg thanks for the review. Fixed most of them, just the env var to make a decision on. Also, slightly concerned the codecov bot and I don't agree on what the test coverage actually is - known issues with it, or tests not getting executed?

@jack-berg ready for another review now I think, thanks. No idea why apiCmp suddenly decided to sulk though.

Its an artifact of a small issue with the 1.50.0 release. See #7344 for details. After that is merged, we can merge main and should be good.

Thanks!
