Adding MimeHandlerView.
This GuestView type would be used to render out of process pdf through extension.
This introduces BrowserPluginDelegate in content/renderer,
because we need a way to create a MimeHandlerView guest (extensions/ concept)
from BrowserPlugin (content/ concept).
MimeHandlerView is behind --enable-mime-handler-view flag.
BUG=303491
Test=Apply http://crrev.com/392813003/ on top of this CL,
Launch chrome with --out-of-process-pdf flag and --enable-mime-handler-view flag
Navigate to a PDF
Check PDF is served using BrowserPlugin, probably easier to see process associated with the BrowserPlugin from Chrome's task manager.
