science/libtensorflow1: Add new port

C API for TensorFlow, an open source platform for machine learning

TensorFlow is an end-to-end open source platform for machine learning.
It has a comprehensive, flexible ecosystem of tools, libraries, and
community resources that lets researchers push the state-of-the-art in
ML and developers easily build and deploy ML-powered applications.
The TensorFlow C API is typically a requirement of TensorFlow APIs in
other languages such as Go and Rust.

This is version 1 of the API, which is deprecated but still widely used.

+TensorFlow is an end-to-end open source platform for machine learning. It has a
+comprehensive, flexible ecosystem of tools, libraries, and community resources
+that lets researchers push the state-of-the-art in ML and developers easily
+build and deploy ML-powered applications. The TensorFlow C API is typically a
+requirement of TensorFlow APIs in other languages such as Go and Rust.
+
+This is version 1 of the API, which is deprecated but still widely used.
