(core) Raw renames

Summary:
A new way for renaming tables.

  - There is a new popup to rename section (where you can also rename the table)
  - Renaming/Deleting page doesn't modify/delete the table.
  - Renaming table can rename a page if the names match (and the page contains a section with that table).
  - User can rename table in Raw Data UI in two ways - either on the listing or by using the section name popup
  - As before, there is no way to change tableId - it is derived from a table name.
  - When the section name is empty the table name is shown instead.
  - White space for section name is allowed (to discuss) - so the user can just paste '   '.
  - Empty name for a page is not allowed (but white space is).
  - Some bugs related to deleting tables with attached summary tables (and with undoing this operation) were fixed (but not all of them yet).

Test Plan: Updated tests.
