3D View: move deselect all logic into an option

This removes `VIEW3D_OT_select_or_deselect_all`, adding a
deselect_all option to the `VIEW3D_OT_select` operator.

- Add utility functions to simplify de-selecting all.

- Return true from selection functions when they change the selection
  to avoid redundant updates.

- Use arrays of bases when passing objects between selection utility
  functions since some users require bases.

- Fix logical error in box selection that updated all objects after
  the first hit.
