Original description

What change would like to see?

The keywords.txt file should come from the active core and variant, rather than being globally defined. (Both in addition to the per-library keywords.txt files). That way, the syntax highlighting will be correct, even for cores with differing APIs.

I believe #3847 at least partially solves this issue. It provides keywords.txt at the architecture directory level, for all cores and variants within an architecture folder.

Perhaps that's good enough?

If not, at least it lays the groundwork to re-read keywords at runtime when boards change....
