This CL removes the last (major) Windows specific part out of the focus manager.

It was previously landed and reverted because it broke the reliability tests.
http://codereview.chromium.org/125148

The breakage was caused by constrained windows not getting a hold of the FocusManager when in unparented tabs.
The fix is to ensure unparented tab still have a way to access their FocusManager for proper closure.
Files changed from the previous patch that need reviewing:
native_tab_contents_container_win.cc
tab_contents_view_win.h
tab_contents_view_win.cc

BUG=None
TEST=Run all tests (unit, ui, interactive). Extensively test the focus in Chrome.
