Add bulk-load of selected drawings' annotations (#8525)

SHIFT+CTRL+CLICK on Activate Drawing now imports the
annotations of all selected drawings without switching
the active view or camera, then selects their cameras with
the first as active. SHIFT+CTRL+ALT+CLICK also selects the
loaded annotation objects. The drawing camera is imported
when missing so annotations land in the correct collection.
Loading is idempotent.
