XR: Add "selection eye" session setting

The "selection eye" is the XR eye (view) used for 3D-to-2D projection.
Its parameters are used to override the window view when selecting
with VR controllers.

Operators: Add modal_3d() and implement for box select

This follows the same logic as invoke_3d(). That is, we wrap an
operator's modal() with modal_3d() and project 3D controller coords to
2D mouse coords.

XR: Remove "replace existing" param from action bindings creation

Since action bindings are only created once at the beginning of an XR
session, overwriting all existing bindings will not be needed.

Fix: Use correct add-on branch for 'make update'

Credit to Julian Eisel for the fix.

Operators: Add invoke_3d() and implement for VIEW3D_OT_select
