[Feature Request] Profile datapacks/integrate perf output

[disconsented]

Description

Quite often I'll find profiles like this one No01i25Mgv.zip where datapacks are a significant issue, but, it's not clear which one it is.

By contrast, /perf can tell us this profiling.txt, they're just awful to read.

[04] |   |   |   |   scheduledFunctions(84/1) - 30.09%/20.23%

Proposed Behaviour

Personally, I think it'd be ideal if we could find a way to represent the work per data pack within the regular views, but I can see that being undesirable.

Alternatively, being able to have spark capture and represent these would be a great help at debugging quite common performance pitfalls.
