feat(node): Allow to pass registerEsmLoaderHooks to preload (#12998)

As mentioned in here:
#12912 (comment)
there is no way today to exclude/include esm modules when preloading
today.

This PR adds the option to pass `registerEsmLoaderHooks` as option to
`preloadOpenTelemetry`, which allows to exclude/include packages there
as well. Users can then write their own custom `preload` script and
configure this there, if wanted.

## Naming

I chose to use the same option naming here than for `init`, although the
semantics are a bit different - here we can't actually disable the
wrapping (because that's the only reason to even call this). We can also
use a different name if we want, but I thought this would maybe be
easier to understand that this is the same thing 🤔
