fix(tvix/castore/grpc/blob): skip_all fields in instrument r/7659

This only contains the outer metadata wrapping, and that's not too interesting:

> Request { metadata: MetadataMap { headers: {"content-type":
> "application/grpc", "user-agent": "grpc-go/1.60.1", "te": "trailers",
> "grpc-accept-encoding": "gzip"} }, message: Streaming, extensions:
> Extensions }

Drop these fields for now, and rely on the underlying implementations to
add instrumentation for the application-specific fields.

Log errors in some places where we didn't so far.
