Matthias van de Meent dab96a6eb1 Add more timing histogram and gauge metrics to the Neon extension (#9116 )

We now also track:

- Number of PS IOs in-flight
- Number of pages cached by smgr prefetch implementation
- IO timing histograms for LFC reads and writes, per IO issued

## Problem

There's little insight into the timing metrics of LFC, and what the
prefetch state of each backend is.

This changes that, by measuring (and subsequently exposing) these data
points.

## Summary of changes

- Extract IOHistogram as separate type, rather than a collection of
fields on NeonMetrics
- others, see items above.
