This change implements a first pass in the effort to remove the dependency of PlatformDevice within Chrome. The Skia library now provides multiple back-ends for the SkDevice class, so PlatformDevice's inheritance of SkDevice, and the assumption of instances of PlatformDevice limits the use of these new back-ends.

A new set of helper functions is provided for the PlatformDevice entry points.  Upon construction of a PlatformDevice, a pointer to the interface is cached in the parent SkDevice's SkMetaData.  The new helper functions forward calls to the interface cached in the metadata.

BUG=NONE
TEST=NONE
