[APM] Latency correlations: Move progress bar loader into the correlation results table and move the refresh option with it.

[formgeist]

Summary

Moved over from meta issue: #102499

It'd be preferable to have the loader sit in the context of the table of correlations results and give the user to refresh near the table as well.

I don't think this sort numerical progression loading indicator is available out of the box for EUI basic table (looks like it's only infinite loading to indicate whether table is loading or not). Do we have something like this already implemented inside APM?

[formgeist]

@qn895 I think we're using the infinite loader in our tables too. Does it matter to the user if the loader is numerical progression or inifite? They can interact with the table either way.

I think the numerical progression is useful for the user. Calculations could take several minutes on reasonably sized data. The user should understand if they are part way through the analysis or nearing its completion. Suggest we leave with progression loading indicator for 7.14.

OK, let's keep it as is for now

Closing as we'll keep the progressive loader over the continuous loading indicator.
