[FEATURE] Add new TypoScript condition `workspace`

A new TypoScript condition `workspace` has been added which allows
checking of several workspace parameters against a given expression.
Currently, only workspace id and state can be used within conditions.

Example:

  [workspace.workspaceId === 0]
    # This matches if the current workspace id equals 0
  [end]

  [workspace.isLive]
    # This can be used to check if the current workspace is live
  [end]

  [workspace.isOffline]
    # This can be used to check if the current workspace is offline
  [end]

Resolves: #90203
