feat(tvix/glue): implement builtins.toFile r/8313

We currently only had a dummy implementation that didn't actually
persist the files in the store(s).

Copy the contents to the BlobService, and do the output path calculation
as part of the upload.
Use the plain context elements to construct the references.
