codeintel: Update bundle manager client to target upload store

Created by: efritz

Update the client that talks to the bundle manager to get/upload LSIF upload data in the upload store rather than the bundle manager disk. This closes https://github.com/sourcegraph/sourcegraph/issues/14826.

Other changes:

• Update enterprise/frontend and precise-code-intel-worker processes to connect to the upload store
• Promote file size from int -> int64 where over-constrained
• Add missing parameter required by new store for StitchParts operations

Deployment environments must be updated to point to a MinIO container or GCS (for dot-com) before this lands.
