ci: run CodeQL with build-mode none

Autobuild compiled the whole test suite. The resulting database was so large that the hosted runner repeatedly lost communication with the server while importing the TRAP files (about 80 minutes in), which left failed CodeQL analyses on develop and on pull requests. Analyze the sources without building them instead. Signed-off-by: Niels Lohmann <mail@nlohmann.me>
