[ML] EUI Visual Refresh (tokens) (elastic#203518)

## Summary

Part of elastic#199715 (EUI Visual Refresh).

Recommend to review with white-space diff disabled:
https://github.com/elastic/kibana/pull/203518/files?w=1

- All references to renamed tokens have been updated to use the new
token name.
- All usage of color palette tokens and functions now pull from the
theme, and correctly update to use new colors when the theme changes
from Borealis to Amsterdam and vice versa.
- Migrated some data visualizer related SCSS to emotion, part of
elastic#140695.
- It makes use of EUI's own `useEuiTheme()` instead of our own hook
variants. So this gets rid of `useCurrentEuiThemeVars()`,
`useFieldStatsFlyoutThemeVars()`, `useCurrentEuiTheme()`,
`useCurrentThemeVars()`.
- Renamed components used to edit Anomaly Detection jobs from
`JobDetails`, `Detectors`, `Datafeed` to `EditJobDetailsTab`,
`EditDetectorsTab`, `EditDatafeedTab` to make them less ambiguous.
- Added unit tests for `ner_output.tsx`.
- Adds checks to pick `euiColorVis*` colors suitable for the theme.

----

Some of our code used colors like `euiColorVis5_behindText`. In Borealis
`*_behindText` is no longer available since the original colors like
`euiColorVis5` have been updated to be suitable to be used behind text.
For that reason and for simplicity's sake I removed the border from the
custom badges we use to render NER items:
