cc: Remove redundant overlay arguments

Whether or not a quad can be made into an overlay is dependent on
whether there is a GLImage backing the texture resources that the quad
uses.

Prior to this patch, this information was passed along to the layer or
quad via a side-channel, in the form of a "allow overlay" argument.

Now, store this information in the cc::Resource, in particular, through
the cc::TextureMailbox that it is created from, and have the overlay
strategy query the property of the cc::Resource.

Add appropriate plumbing of the parameters from the cc::TextureMailbox,
through the cc::Resource, to cc::TransferableResource, and finally to
a cc::Resource in other compositors.
