[RFC,v2,12/24] Makefile: extract script to generate clar declarations

Commit Message

Patrick Steinhardt Oct. 9, 2024, 2:56 p.m. UTC

Extract the script to generate function declarations for the clar unit
testing framework into a standalone script. This is done such that we
can reuse it in other build systems.
