[Lens] Add custom formatter within the Lens editor

[dej611]

Summary

Fixes #157900

Goal of this PR:

• simplify Metric formatting logic (only duration formats are now "enhanced")
• add a new Compact option for the existing Lens formatters (Bytes and Bits excluded as they compact already)

• provide a full custom formatter based on numeral.js

Previous migration changes - removed now

## Migration changes

The tricky part here comes with the format migration for the new metric, as there's no easy way to detect what "Default" means, not having access to field formatters during migrations.
There are two possibilities, as far as I can see, on the topic:

1. when default format is detected, assume it's a number format with the compact feature turned on
2. when default format is detected, assume nothing and let the Kibana default format go on (no compact)

In this PR I've implemented the 2nd migration strategy.
Here's a visual example of the problem.

Original dashboard

Option 1

Option 2 (implemented)

Release notes

Default format in Lens will apply dataView field format as usual now in new Metric visualization.

Marco says this would be a code smell in prod code, but this double type cast is ok in a test.
