refactor(tvix/store): use read_all_and_chunk in gRPC blobservice r/5959

This was the last piece of code using BlobWriter.

We can also use `read_all_and_chunk`, it's just requires a bit more
plumbing:

 - The data coming from the client (stream) needs to be mapped (we
   extract the .data field).
 - The stream needs to be turned into an (async) reader
 - The reader needs to be made sync, and that code using the sync reader
   needs to be in a `task::spawn_blocking`.
