chore: export shimmer functions

[Joozty]

Which problem is this PR solving?

I need to override some functionality in my code. I want to use new wrapper functions instead of relying on the old shimmer, which is incorrectly typed. I added an export so that I can use these new functions in my derived code, which is heavily based on OTel.

I also don't have a strong preference. Though if we do export these, we should also deprecate the re-exports on the instrumentation base classes so that people are not left wondering which one is the "correct" one to use now.

@pichlermarc can you please point out to me where this should be deprecated?

@Joozty sorry for the late response - the ones I meant that we should deprecate are here on InstrumentationAbstract:
