For the cases where frontend/buildkit doesn't support new Git Querystring format, allow resolving the URL into LLB on client side and then build from input. Note that this produces slightly different provenance where context is not set as string, so added opt-in via environment variable for now. Signed-off-by: Tonis Tiigi <tonistiigi@gmail.com>

We will likely use it in Docker Github Actions so that we can use checksum and ref together in all the builds by default.
