Change ProcessBreakBeforeOrAfter() to return an Optional struct.

Instead of returning a bool and have 3 out parameters. Along the way:

- Make ProcessBreakBeforeOrAfter() private. Expose ProcessBreakBefore()
  and ProcessBreakAfter() public methods.
- Change CXFA_LayoutPageMgr::ExecuteBreakBeforeOrAfter() to return a
  struct.
- Mark a bunch of methods, members, and parameters const.
