CI: Don't run bootstrap if we restored from cache (#32610)

* CI: Don't run bootstrap if we restored from cache

Handle caching and log upload directly within the bootstrap action, and don't
perform the actual bootstrap if we have a cache hit. Include the platform name
in the cache key.

* Silabs requirements are for non-Docker builds
