Fixes for views_unittests on Mac after InputMethodBridge removal (DO NOT COMMIT)

Patch on top of https://codereview.chromium.org/1177503003

Changes for the new recipe-based trybots means views_unittests is no
longer compiled on the default trybots. However, it looks like it's
still build in the waterfall :/

(e.g. builds on
http://build.chromium.org/p/chromium.mac/builders/Mac%20Builder )

Hi Shu,
 This is not for landing, but I think these changes will be needed for your CL
in https://codereview.chromium.org/1177503003 to stick after landing.

Not sure if it's the right fix (still wrapping my head around all the IME stuff
:). Happy to try out any suggestions you may have on my local machine. Didn't
get around to manual testing this today, but this will fix all the Textfield
unittests which will fail on Mac without this (as well as not compile due to the
aura dependency in textfield_unittest.cc)

views_unittests isn't quite ready to run on Mac. It used to be that all the
trybots would compile views_unittests on Mac and I was just fixing the
occasional test failure (typically just something I hadn't implemented yet). But
that all changed recently (trybots now only compile the tests that run), but it
looks like it hasn't fully caught on in the waterfall.

I'm working hard on getting views_unittests running on Mac so that the trybots
will pick this up as well. It is getting close.

ui/views/cocoa/bridged_native_widget.mm:710: // Delegate is NULL because Mac IME
does not need DispatchKeyEventPostIME
I think this was true (and worked OK) when InputMethodBridge was calling
DispatchKeyEventPostIME, but now that InputMethod calls it, the delegate is
needed.

Thanks for catching the issue!

I've merged this to cl https://codereview.chromium.org/1177503003.
