Remove GrPipelineBuilder from getPathRenderer call

Logically this CL:

Moves the PathRendererChain from GrContext to GrDrawManager
   - this was needed to untangled the Path-Chain/Renderer header mess
   - this entailed adding getDrawingMgr so the CMM could access the PathRenderingChain
   - this also entailed re-adding freeGpuResources to the GrDrawingMgr
Moves the CanDrawArgs struct up stack
Removes the GrPipelineBuilder from the CanDrawArgs struct
