Dump additional details about the gpu resources.

GpuResources now dump optional string values that describe the type and
category of the resource.  The type provides a description of the kind
of resource it is (e.g. texture, buffer object, stencil, etc.) and the
category describes what the resource is currently tasked to do (e.g.
path masks, images, scratch, etc.)

This CL also refactors the dump logic in an attempt to consolidate
duplicated code into GrGpuResources.cpp.
