Fix #7681: Fix isolate_objects ignoring hide_select/hide_viewport (#7710)

Objects with hide_select=True could not be selected during
isolation, causing hide_view_set to incorrectly hide them.
Objects with hide_viewport=True had their H-key hide state
modified as a side effect of hide_view_clear/hide_view_set.
Both are now left unaffected by bim.activate_drawing.
