Add tabs to the right panel (#12672)

* Create new method for header button behaviour

With the introduction of tabs, the behaviour of the header buttons is
changed as follows:
- Close any right panel if open
- Open the correct right panel if no panel was open before

The old method (and behaviour) is retained as showOrHidePhase.

* Implement tabs in the right panel

There are three tabs: Info, People and Threads

* Remove unwanted code from RoomSummaryCard

- Remove the menu item for opening the memberlist since that is now
  taken of by the tabs.
- Remove the close button

* Remove code for focusing close button from tac item

See https://github.com/matrix-org/matrix-react-sdk/pull/12410

There's no longer a close button to focus so we instead focus the thread
tab. This is done in RightPaneltabs.tsx so we just need to remove this
code.

* Introduce a room info icon to the header

This was previously present in the legacy room header but not in the new
header.

* BaseCard changes

- Adds id, ariaLabelledBy and role props to implement tab accessibility.
- Adds hideHeaderButtons prop to hide header buttons (think back and
  close buttons).
- Change confusing header rendering code:
  header is not rendered ONLY when no header is passed AND
  hideHeaderButtons is true.

* Refactor repeated code into function

Created a new function createSpaceScopeHeader which returns the
component if the room is a space room. Previously this code was
duplicated in every component that uses SpaceScopeHeader component.

* Pass BaseCard attributes and use helper function

Actually using the code from the last two commits

* Add, update and remove tests/screenshots/snapshots

* Fix distance between search bar and tabs

* Update compound

* Update screenshots/snapshots
