Scott Wolchok ade8fee512 Use c10 version of half/bfloat16 in executorch (#144111)
Summary:
X-link: https://github.com/pytorch/executorch/pull/7040

Accomplished by importing relevant files from c10 into
executorch/runtime/core/portable_type/c10, and then using `using` in
the top-level ExecuTorch headers. This approach should keep the
ExecuTorch build hermetic for embedded use cases. In the future, we
should add a CI job to ensure the c10 files stay identical to the
PyTorch ones.
