Edit Mesh: tag the object data for updating instead of the object

When editing vertices with number buttons, tag the mesh, not the object.

This prevents the evaluated mesh being re-created for the object
and is correct as the mesh is being edited not the object.

Note that all tags for updating object geometry should be checked
to see if this change should be applied there too.

>From a simple test on a high-poly mesh this gives around 1.3x
overall speedup.
