Switch tf.keras.Model.save_weights to TensorFlow format for graph networks.

Some tweaks to support loading checkpoints into modified Python programs.

Relaxes the Checkpointable consistency check for object matching: if the same
object in the checkpoint matches two different Python objects, it will just
choose the first one that matches (based on whichever traversal of the Python
dependency graph it's doing). assert_consumed() on the status object will fail,
but this gives users the option of continuing anyway.

Adds a "weight-bearing layer index" dependency to graph networks which skips
Layers without weights, in addition to the regular layer index. This allows
users to add Layers without weights while not breaking checkpoints, as they
could when matching with flattened weights from HDF5 format.

Eventually I'd like to add a dependency structure which matches the topology of
the graph itself (so a Layer would have checkpoint dependencies on other Layers
it outputs to), but there are some subtleties before that's useful (it'd need
something like a secondary check that the Python classes match). I think the
scheme in this CL is robust enough for general use, and adding more dependencies
later can make it more robust now that users won't run into consistency check
errors (previously more dependencies would only make matching more picky).

`PartitionedCallOp`: An op for executing multi-device functions.

A `PartitionedCallOp` allows for execution of functions across multiple devices
but within a single process. It proceeds by placing and partitioning the graph
underlying a given function body, instantiating for each partitioned subgraph a
function. The yielded function shards, which together are equivalent to the
original function, are then executed.
