[Icons] Remove persisted deprecated aliases

This is a follow-up to https://github.com/elastic/eui/issues/9561. The purpose is to remove the leftover deprecated icon aliases:

- `alert` (new handle: `warning`)
- `compute` (new handle: `processor`)
- `editorComment` (new handle: `comment`)
- `list` (new handle: `listBullet`)
- `mapMarker` (new handle: `waypoint`)
- `pinFilled` (new handle: `pinFill`)
- `search` (new handle: `magnify`)
- `starEmpty` (new handle: `star`)
- `starFilled` (new handle: `starFill`)
- `temperature` (new handle: `thermometer`)
- `visArea` (new handle: `chartArea`)
- `visBarVertical` (new handle: `chartBarVertical`)
- `visGauge` (new handle: `chartGauge`)
- `visLine` (new handle: `chartLine`)
- `visPie` (new handle: `chartPie`)
- `visTable` (new handle: `table`)

They were left to avoid breaking persisted cases in Kibana. We can only remove them once a migration mechanism is in place:

Start by reading follow-up issue 9561 and the linked Kibana discussion, then review the listed Kibana files to understand where the deprecated aliases are persisted. Confirm that a migration mechanism is in place before removing the aliases from EUI; done means the listed deprecated handles can be removed without breaking persisted Kibana cases.
