This is a reland of 5a2de5e72f
This is part one of two CLs. In this CL, I put a
sk_sp<GrArenas> on GrRenderTargetProxy where GrArenas wraps
a SkArenaAlloc to add ref counting. Creating
a GrOpsTask shares the GrArenas with the ops task. When an
GrOpsTask is destroyed, it nulls out the fArenas sk_sp on
the GrRenderTargetProxy to limit the life span of the arenas.
New plumbing was added to GR_DRAW_OP_TEST_DEFINE to allow a
proper GrSurfaceDrawContext to be passed to GrAtlasTextOp's
GR_DRAW_OP_TEST_DEFINE so the arena will have a proper lifetime.
The second CL will work on replacing GrOpsTask's fAllocators
system with the shared arena.
