Regenerate the FOU uAPI header from the YAML spec.

The flags now come before attributes which use them,
and the comments for type disappear (coders should look
at the spec instead).  

Sorry I missed the whole history of this topic. Wanted to ask: if we can
generate these headers and even C files, why ship the generated with the
source code and not generate them during building? Or it's slow and/or
requires some software etc.?

Currently it requires python 3 (3.6+, I'd think?).

Python is currently not documented as a build requirement in
Documentation/process/changes.rst afaict.

Yes, I wanted to avoid bundling in changes which could be controversial.
Whether code is generated during build or committed is something we can
revisit at any point.
