refactor(tvix/castore/*): drop utils.rs and grpc directorysvc tests r/7795

This drops pretty much all of castore/utils.rs.

There were only two things left in there, both a bit messy and only used
for tests:

Some `gen_*_service()` helper functions. These can be expressed by
`from_addr("memory://")`.

The other thing was some plumbing code to test the gRPC layer, by
exposing a in-memory implementation via gRPC, and then connecting to
that channel via a gRPC client again.

Previous CLs moved the connection setup code to
{directory,blob}service::tests::utils, close to where we exercise them,
the new rstest-based tests.

The tests interacting directly on the gRPC types are removed, all
scenarios that were in there show now be covered through the rstest ones
on the trait level.
