Apply the same fix for T32214 (edge-select failing) to bones which also failed when their end-points were outside of the view. - Add V3D_PROJ_TEST_CLIP_CONTENT support for edit & pose bone iterator and use for selection operators. - Remove unnecessarily complicated checks with pose-mode lasso tagging. - Correct error in pose-mode LassoSelectUserData.is_changed (currently harmless as it's not read back).
