Make the new search dialog accessible

[kittykat]

The new search dialog needs to be accessible, especially for screen reader users.

The user ticket gives us the following tasks:

• The search input box is not visible to screenreaders when opening the new search
  Fix accessibility around the room list treeview and new search beta matrix-org/matrix-react-sdk#7856
• The room list / space list can not be reached via a shortcut directly
• Rooms and Users should have a context menu in search results the same as if they’re shown in a room or member list

• The room list / space list can not be reached via a shortcut directly

Maybe I am misunderstanding, but I don't understand why this is relevant specifically to the new search? The room list and space list are separate features which currently don't have shortcuts, do they? But A user can use a keyboard shortcut cmd + f in chrome to find text in the UI for room list - or is that taken up by something else in element?

• Rooms and Users should have a context menu in search results the same as if they’re shown in a room or member list

As in, give them these icons/the options within them?

Because previously Ctrl/Cmd K would take you to the room filter field atop the room list from where you could tab/down arrow into the room list or shift tab into the space panel.

But A user can use a keyboard shortcut cmd + f in chrome to find text in the UI for room list - or is that taken up by something else in element?

Electron App doesn't have Cmd + F, optionally you can bind it to message search, this is also not a hugely accessible solution as the Space Panel has no text at all.

We'll move the discussion regarding the context menus and the requested shortcuts for the space/room list into separate issues
