Revert r156303 as non-Aura Metro mode is gone

We no longer need to support TSF in the browser code. Now TSF-related code
is completely consolidated into the metro_driver process and the browser
process doesn't need to know about TSF any more.

Note: TSF-related code remaining in base/win/metro.{cc, h} and
content/browser/browser_main_runner.{h, cc} will be reverted by subsequent CLs.

Hi Carlos and Scott,
Could you take a look at following files?

cpu:
  base/win/metro.h
  base/win/metro.cc
sky:
  content/*

[sky, 2014-01-30 04:24:30]

LGTM

[cpu_(ooo_6.6-7.5), 2014-01-31 21:40:11]

lgtm

How about the TSF code that hooks the message loop (TextServicesMessageFilter),
is that going away?

Oops, sorry, wrong one. yukawa said he was going to look at the rest of the tidy
up for 34 in that review though.

Yes, it will be going away in the subsequent CLs.
