The element does not have to enforce layout when the type attribute is set to image

According to the spec1, the <embed> element represents nothing
in those conditions:

The element has neither a src attribute nor a type attribute.
The element has a media element ancestor.
The element has an ancestor object element that is not showing
its fallback content.
There is no requirement for ImageType to enforce layout in the spec.
So removed the logic of forcing layout when type is set to image.

This patch also moves "embed-represent-nothing-04.html" to
"embed-in-object-fallback-image.html".
And "embed-represent-nothing-04.html is failing in all browsers.
According to the spec2:

If the data attribute is present and its value is not the empty
string, then: ...
Fallback: The object element represents the element's children.
This is the element's fallback content.
If the object element does not have a data attribute,
its children should be used as fallback content.
The test case in "embed-represent-nothing-04.html", object does not
have a data attribute, so it should fallback, show it's children.
