GTK: Move CairoCachedSurface from being owned by GtkThemeService to gfx::Image.

CairoCachedSurfaces are representations of a GdkPixbuf that live on the display
server instead of in process. GtkThemeService currently returns a
CairoCachedSurface for a (IDR#, Display). Instead, make gfx::Image keep
CairoCachedSurfaces as a representation and make CairoCachedSurface work on any
display, keeping the mapping to display server resources as an implementation
detail.

This has the benefit of:

- You don't need to go through GtkThemeService to access all resources,
  simplifying the code in some places and allowing sharing of static images
  across profiles.
- This will let us (in the future) remove several image conversions in the GTK
  port.

This is part 1. Part 2 will remove the custom CairoCachedSurface calls from
GtkThemeService.
