Fix RenderWidgetHost visibility for tabs loaded in background.

This patch sets the visibility state of RenderFrameHosts being created in
RenderFrameHostManager, fixing a regression introduced in
http://crrev.com/241423 which made RenderWidgets being created in background
have incorrect visibility state.

The ChromeRenderProcessHostTest.Backgrounding browsertest is extended to cover
this case.

Credits to nasko@chromium.org for finding the fix.

Clean up StatusBubbleViews::StatusView some:

* We dont really use anything in Label, so don't inherit from it, just inherit
  from View.
* Be consistent about referring to "states" rather than sometimes calling them
  "stages".
* Enums go before constructors.
* Don't inline complex functions in non-test code.
* Cheap accessors should be named unix_hacker()-style.
* Consistently use FontList in place of Font everywhere.
