Add Symbol.isSuperAccessor to reflection API

Alternatively, we could make sure to set the Artifact flag (which doesn't do anything at runtime but is used to signal to javac that this method should not be called from user code) on super accessors, default getters, etc.

I think my suggestion from #13388 (comment) is still the way to go, unless there's a good reason to specifically care about super accessors from reflection?

[nicolasstucki]

@pikinier20 could you try the alternative solution that does not require this addition?

[pikinier20]

@nicolasstucki Do you think it's worth to add such method to API?

[nicolasstucki]

I think it is worth it even if there is another if later we manage to also do this via flags. We will still have code generated before the addition of the flag that will need to fall back to this check.

@pikinier20 you can remove the MiMa filters as they are not needed anymore. Instead you have to run locally scala3-bootstrapped/testCompilation tests/run-custom-args/tasty-inspector/stdlibExperimentalDefinitions.scala and update the list there.

What's the current status with this. Are you still waiting on a review @pikinier20? @nicolasstucki is this something you can return back to to review?

[nicolasstucki]

I think we should rebase this and merge it. It looks good to me.
