Marco Zehe 78555ed422 Make reaction buttons more accessible
Fixes vector-im/riot-web/issues/11608.

This patch:

1. Turns the container of reaction buttons into a toolbar.
2. Makes each button span into a button with a tabindex and an aria-label.
3. Constructs an alternative label that differs slightly from the text displayed by the tool tip:
   * It uses the names of the people who reacted.
   * It puts a space before the "reacted with" text.
   * It uses the actual emoji characters, not the converted colon-delimited shortNames, because the emojis usually tell blind users more about the expression.
   * It omits the number of reactions, since that information is already conveyed by the names.
