(setup for datagrid button cleanup)

- `textProps &&` is required now for typing, to avoid `false` shenanigans

- misc/optional cleanup while we're here and thinking about badges in buttons

+ update downstream `EuiSearchBar` snapshots

- this allows us to remove the extra flex group/wrappers completely, as the text and badge node now sit as siblings and automatically inherit button content flex layout

- also lets us correctly text truncate the text content, if needed

- TBH, the types are so simple I don't anticipate many consumers needing it, and I'd rather keep them where they're used. If consumers really do need it they can import directly from this file or use PropsOf

- use `FC<>` typing to match rest of EUI

- add styles for underlining text, but not the badge

- fix cursor on badge

- add `className` hooks to both text & badge nodes in case consumers want to customize their CSS

- misc/consistency - rename props (rest, classes, etc) to match other EUI components

- in favor of `.euiDataGridToolbarControl` (now that we have a specific component for this)

- remove the active `font-weight` as well, since it's no longer being used

- remove `.euiDataGrid__controlBtn` from the icon buttons as well - they're not consistently applied and they're not really doing anything, nor are they being hooked into in Kibana for the icon buttons

- replace fullscreen hook with `aria-pressed` instead

+ snapshot updates

- make unit tests more focused
- add specific assertions in addition to snapshots
- add test for new `textProps` behavior

- make the text assertion more specific, now that we can look at the badge node

+ simplify logic of columns badge

- This is too noisy for a datagrid-specific PR, I'll cherry-pick it out and open up a follow-up PR once this one merges

This reverts commit 3408cfb.

- update copy + props tables

- gets me every time...
