Add a query function for the scaling feature.

Add a query function for the scaling feature.

We need to be able to query whether scaling is supported before creating a
Graphics2D object so we know which code path to use. This just adds a function
to do that checking.

I also renamed Graphics2DDev to Graphics2D_Dev for consistency with the other
Dev wrapper objects.

File ppapi/cpp/dev/graphics_2d_dev.h (right):

ppapi/cpp/dev/graphics_2d_dev.h:14: class Graphics2D_Dev : public Graphics2D {
Just a reminder that we'll want to quickly rev clients to account for the rename
(e.g. PDF Viewer)

Should we do both this and ViewDev -> View_Dev at the same time then? I don't
have a strong opinion either way.
