Move PlatformCanvas and PlatformDevice from base/gfx to webkit/port. I left header files in the original locations that include the ones in the new location so I don't have to change all the includes in Chrome at once. These will be removed later.

I kept the names, indenting, and the namespaces the same for now. I will also be cleaning this up in separate passes.
