Support DWM switching.

This completes the collapsing of window types and browser frames around a single class: views::Window. CustomFrameWindow is removed with this change.

The Browser window is represented by a single views::Window subclass: BrowserFrame, which replaces both AeroGlassFrame and OpaqueFrame.

NonClientView is now a container of two sibling classes - the Window's ClientView (in the Browser's case, BrowserView), and a NonClientFrameView subclass, which provides the rendering for the non-client portions of the window. These Views are siblings rather than the ClientView a child of the NonClientFrameView because when the DWM is toggled, the ClientView would have to be re-parented. Many Views make the assumption they are only inserted into a View hierarchy once, and so this is problematic. By having the views be siblings, this is avoided.

With this in mind, all of the former NonClientViews now become NonClientFrameView subclasses:

DefaultNonClientView -> CustomFrameView
(non-existent, NonClientView) -> NativeFrameView
AeroGlassNonClientView -> GlassBrowserFrameView
OpaqueNonClientView -> OpaqueBrowserFrameView

The latter two derive from NonClientFrameView via BrowserNonClientFrameView, which adds some extras.

I also had to modify the TabRenderer class to know how to drop its cache of tab background images when the theme changes since it uses different ones for Glass and non-Glass.

This change also fixes a few non-client flicker issues relating to window non-client activation by using more ScopedRedrawLocks. (Touches info_bubble.cc, window.cc)
