GCC LLM policy adopted

Key points from my perspective are:

- It clearly distinguishes including LLM output in what gets committed
  from other uses of LLMs for software development, as I have been
  repeatedly advocating is important, without much uptake.

- The focus is on copyrightability/licenseability.

- It will be reviewed when the result of the FSF's consultation with
  lawyers comes out, in light of that.
