`west ncs-sbom` is REALLY slow. It turns out it runs `scancode` on every source file in the build (working backwards from object files in the build directory), single-threaded- and every time `scancode` starts, it takes a few seconds to load its license database into memory. Pretty annoying. Luckily there's an option for a cache, let's try it out.

On a cold run,
west ncs-sbomtakes about 12 minutes.With the cache warmed up, it's about 4 minutes.
Since we're using github's cache, these will expire after 7 days afaik :/ but at least repeated builds will be speedy.
