Reland: Fix and re-enable some browser focus interactive ui tests.

The original r272259 was reverted for test failures on Windows XP.
http://build.chromium.org/p/chromium.win/builders/XP%20Tests%20%281%29/builds/31296

FocusTraversal[OnInterstitial] times out on Windows XP with no output:
[ RUN      ] BrowserFocusTest.FocusTraversal
[3796:3464:0522/144031:ERROR:gpu_info_collector_win.cc(103)] Can't retrieve a valid WinSAT assessment.
[3796:380:0522/144031:WARNING:embedded_test_server.cc(230)] Request not handled. Returning 404: /favicon.ico
[397/398] BrowserFocusTest.FocusTraversal (TIMED OUT)

As InterstitialFocus passes, TestFocusTraversal is probably at fault.
I disabled that helper on XP with a comment for Issue 376635.
The original description is otherwise accurate as follows:

========================================

Fix FocusTraversal[OnInterstitial] except *OnInterstitial on Mac :(
Fix InterstitialFocus and FindFocusTest.

Add a TestFocusTraversal helper function consolidated from tests.
Simplify TestInterstitialPage and add a WaitForInterstitial helper.
Move test server init to a common SetUpOnMainThread.
Remove unnecessary helpers and includes.

TODO(followup): Fix more tests!
