Wildcard <Icon /> accessibility. `client/browser`, `client/branded`, `client/jetbrains`, `client/vscode`

Created by: gitstart-sourcegraph

Description

Our Icon component is not currently accessible and will cause issues across our application.

Screen readers will report each icon as "unlabelled image" - which isn't helpful to anyone.

Expected behavior

For decorative icons, we should set aria-hidden="true". This will ensure screen readers completely ignore the icon, as it adds no value to the user journey.

For icons that add useful information to the page, we should set role="img" and title="Some descriptive text". This will ensure screen readers are able to properly understand to meaning of the icon.
