Upgrade EUI to v89.0.0 (elastic#168396)

`v88.5.4`⏩`v89.0.0`

---

## [`89.0.0`](https://github.com/elastic/eui/tree/v89.0.0)

- Added new `pushAnimation` prop to push `EuiFlyout`s, which enables a
slide in animation ([elastic#7239](elastic/eui#7239))
- Updated `EuiComboBox` to use `EuiInputPopover` under the hood
([elastic#7246](elastic/eui#7246))
- Added `inputPopoverProps` to `EuiComboBox`, which allows customizing
the underlying popover
([elastic#7246](elastic/eui#7246))
- Added a new beta `EuiTextBlockTruncate` component for multi-line
truncation ([elastic#7250](elastic/eui#7250))
- Updated `EuiBasicTable` and `EuiInMemoryTable` to support multi-line
truncation. This can be set via `truncateText.lines` in the `columns`
prop. ([elastic#7254](elastic/eui#7254))

**Bug fixes**

- Fixed `EuiFlexGroup` and `EuiFlexGrid`'s `m` gutter size
([elastic#7251](elastic/eui#7251))
- Fixed focus trap rerender issues in `EuiFlyout` with memoization
([elastic#7259](elastic/eui#7259))
- Fixed a visual bug with `EuiContextMenu`'s animation between panels
([elastic#7268](elastic/eui#7268))

**Breaking changes**

- EUI's global body font-size now respects the `font.defaultUnits`
token. This means that the global font size will use the `rem` unit by
default, instead of `px`.
([elastic#7182](elastic/eui#7182))
- Removed exported `accessibleClickKeys`, `comboBoxKeys`, and
`cascadingMenuKeys` services. Use the generic `keys` service instead
([elastic#7256](elastic/eui#7256))
- Removed `EuiColorStops` due to low usage
([elastic#7262](elastic/eui#7262))
- Removed `EuiSuggest`. We recommend using `EuiSelectable` or
`EuiComboBox` instead
([elastic#7263](elastic/eui#7263))
- Removed `euiHeaderAffordForFixed` Sass mixin, and `$euiHeaderHeight`
and `$euiHeaderHeightCompensation` Sass variables. Use the CSS variable
`--var(euiFixedHeadersOffset, 0)` instead.
([elastic#7264](elastic/eui#7264))

**Accessibility**

- When using `rem` or `em` font units, EUI now respects, instead of
ignoring, browser default font sizes set by end users.
