Deduplicate FunctionLibraryDefinition objects in TF to save memory.

This change de-duplicates the two FunctionLibraryDefinition objects that are
created in the context of `tensorflow::DirectSession` when the tensorflow
models are being loaded into the program ahead of inference executions. The
bulk of the memory consumption in the library definition is taken by
shared-pointers, which can be used to remove duplicates and save RAM.
