Enable build profiles for Docker source builds (#4237)

## Proposed Changes

- Allow Docker images to be built with different profiles via e.g. `--build-arg PROFILE=maxperf`.
- Include the build profile in `lighthouse --version`.

## Additional Info

This only affects Docker images built from source. Our published Docker images use `cross`-compiled binaries that get copied into place.
