Fix T75343: Wireframe overylay is not working properly with multiple modifiers

Since rBcf258b02f449, only wires and edges that are mapped to the
original mesh were drawn if the mesh was modified by modifiers.
Above commit was only meant for showing orig wires for paint mask
overlays [where final wireframe is not desired], so now only use
MR_EXTRACT_MAPPED when we are in a paint mode.
