Cleanup program building a bit

This CL:
   now passes the GrProgramDesc as a const&
   returns GrGLProgram as an sk_sp
   makes the parameter ordering more consistent
   makes GrVkPipelineState no longer ref-counted

This is pulled out of the DDL pre-compile CL which touches this portion of the code.
