Make a layer for popup MessageView

Previously all MessageView had an own layer. And now, by http://crrev.com/2849523005, only non-popup MessageView, which is in the message center, has a layer.

But it causes a regression ( http://crbug.com/722647 ) so this CL reverts that part.

This CL breaks swiping on popup but it'll be fixed soon by http://crrev.com/2873553002.

BUG= 722647 
TEST=manual (issue doesn't happen)
