Tool System: use preselect highlight w/ poly-build

- Poly build now uses a new gizmo for pre-selection
  which has the same behavior as loop-cut.

  This replaces hack where mouse-move set the active element
  which was no longer working properly because of missing
  depsgraph updates.

- Multi-object support for poly-build.

- Support for deformed cage.

- Fix error where changing active object wasn't properly
  refreshing the preselect gizmo (for loopcut too).

Currently holding Alt to select non-boundary element's isn't working.
