0029470: Samples - eliminate references to deprecated Local Context from MFC sample

AIS_InteractiveContext::MoveTo(), ::Select(), ::ShiftSelect() now throw
an exception on invalid V3d_View argument instead of returning empty results.
AIS_InteractiveContext::DetectedShape() and ::BeginImmediateDraw() now can
be called without opened Local Context.

Draw Harness - removed unused commands vsetam, vunsetam.
Removed unused methods ViewerTest::StandardModeActivation(), ::PickObject(), PickObjects().
Interactive input of Selection modes 0..7 now redirects to vselmode
instead of removed ViewerTest::StandardModeActivation().
