evas: Fix rare issue with recursive proxy src invisible

Scenario:
  smart {
    text
    proxy -> text, src_invisible
  }
  proxy -> smart

What we should see:
  smart {
    (blank)
    proxy -> text
  }
  proxy -> {
    (blank)
    proxy -> text
  }

What we saw:
  smart {
    (blank)
    proxy -> text
  }
  proxy -> {
    text
    proxy -> text
  }

Solution:
Check in evas render, when we're inside a proxy render, and the
proxy src_invisible flag is on (evas_object_source_visible_set(0),
that we're rendering the object itself to its proxy surface. If not,
it means we're rendering another proxy surface, ie. a parent smart
object's proxy surface.

Still loving evas render.

Fixes T4006.
