Pipe ConfigProto through FLR so that it can be accessed by Ops like PartitionedCallOp.

Also pass the ConfigProto through distributed function calls both in the standard
graph registration mode and in the new eager master setup.

The PFLR stores a std::optional<ConfigProto> instead of a pointer, because it may be created with a pointer that would dangle after its creation.  At the same time, we need to know if a ConfigProto was available at creation time, which is why it's a std::optional.  In contrast, the FLR gets a pointer directly because it is given a valid pointer that will outlast it in all cases.
