Now uses dtype.name to match known-rank case (used dtype previously), and adjusts from [None] to (shape=None).

This will change the string representation e.g. of TensorType(tf.float32, shape=None) from:

tf.float32[None]

to

float32(shape=None).

For reference, a TensorType(tf.float32, shape=[None]) (IE, rank-1 tensor of unknown size) will remain represnted as:

float32[?].

This will be used as the default metric aggregator for most iterative process/eval computation builders provided by TFF learning.

First of a stream of CLs with boilerplate work for sequence executor.

Note that this does not parallelize materializing or merging of child results: those
steps are still serialized.

As an aside, this CL adds a new `main` function for tests running in OSS.
This was necessary in order to use absl flags in OSS C++ tests because OSS
gtest_main intercepts argc and argv but does not parse absl flags. For
details, see https://github.com/google/googletest/issues/3646.

Previously, failure to make `ExecutorValue` instances copy-constructible would result in confusing template instantiation errors. This `static_assert` makes the
requirement explicit and provides the user with a clear, actionable suggestion.

Example error:

```
ERROR: third_party/tensorflow_federated/cc/core/impl/executors/executor.h:230:3 static_assert failed due to requirement 'std::is_copy_constructible<std::unique_ptr<int, std::default_delete<int>>>::value' "`ExecutorValue`s (the type parameter passed to `ExecutorBase`) must be copy-constructible. Consider wrapping with `std::shared_ptr`, `std::shared_future`, or other similar container like: `class MyExecutor: public ExecutorBase<std::shared_ptr<MyExecutorValue>>`"
  static_assert(std::is_copy_constructible<ExecutorValue>::value,

This CL is Step 1 of migrating TFF learning model to the new way of binding metrics. It adds two new attributes: `report_local_unfinalized_metrics` and `metric_finalizers`. The two attributes are not being used yet.

Turn off `abi_tags` in C++ mangled names to be compatible with TensorFlow shared objects bulit for the `tensorflow` pip package.
