Subject : Clean up the RWHVMac to ui::Compositor interface
Author  : ccameron
Commit description:
  
Move the "ui::Compositor's relationship to RWHVMac" state machine
into BrowserCompositorViewMac.

Clarify the state by renaming states from
  Active / Suspended / Destroyed
to
  HasAttachedCompositor / HasDetachedCompositor / HasNoCompositor

Change the thumbnailer's copy requests to be intercepted by the
BrowserCompositorViewMac, and thereby have the copy request
keep the ui::Compositor attached (even if the RenderWidgetHostImpl
is hidden).
