[Lens] Duration formatter follow ups (#162871)

## Summary

Fix #162453 

This PR address few design feedback for the formatter area and adds
supports for the duration formatter within the TSDB -> Lens transition
feature.

List of features:
* new shared component for "synced prepend" in EUI form controls
`Prepend` + `PrependWidthProvider` ✨
* Integrate design feedback within the dimension editor 💄 
  * sync prepend width
  * `Human readable` -> `Friendly` relabel
* add support for duration formatter for the TSVB to Lens feature
  * Fix formatter bug for `Count` operation 🐛 
  * Add tests ✅ 
  * Add external Numeral link for Custom formatter ✨ 
  * Revisit UI for compact switch control 💄 
  * `From` -> `Convert` relabel for duration formatter 💄 
* Hide `Compact` and `Decimals` controls for `Friendly (approximate)`
output selection

### Risk Matrix

Delete this section if it is not applicable to this PR.

Before closing this PR, invite QA, stakeholders, and other developers to
identify risks that should be tested prior to the change/feature
release.

When forming the risk matrix, consider some of the following examples
and how they may potentially impact the change:

| Risk | Probability | Severity | Mitigation/Notes |

|---------------------------|-------------|----------|-------------------------|
| Multiple Spaces&mdash;unexpected behavior in non-default Kibana Space.
| Low | High | Integration tests will verify that all features are still
supported in non-default Kibana Space and when user switches between
spaces. |
| Multiple nodes&mdash;Elasticsearch polling might have race conditions
when multiple Kibana nodes are polling for the same tasks. | High | Low
| Tasks are idempotent, so executing them multiple times will not result
in logical error, but will degrade performance. To test for this case we
add plenty of unit tests around this logic and document manual testing
procedure. |
| Code should gracefully handle cases when feature X or plugin Y are
disabled. | Medium | High | Unit tests will verify that any feature flag
or plugin combination still results in our service operational. |
| [See more potential risk
examples](https://github.com/elastic/kibana/blob/main/RISK_MATRIX.mdx) |
