Update Browser with the current code from the Chromium tree

Synced WebViewBrowserActivity, manifest and resources up to
the state of the Chromium tree at refs/heads/master@{#371018}

Differences from the Chromium version:

  -- WebViewBrowserActivity uses android.util.Log instead of
     org.chromium.base.Log, thus difference in call parameters;

  -- relative class names are used for Activity classes
     in the manifest file.
