Declarative server-side table execution logic that preserves authorization logic

[devinrsmith]

As expressed in the FlightSQL review comment, we should ideally be able to execute server side Table logic that respects the intentions as exposed via io.deephaven.auth.codegen.impl.TableServiceContextualAuthWiring. This is currently a layer that is heavily targeted towards the gRPC / protobuf, so it's not immediately obvious how we can take advantage of this server-side.

One proposal is to create a new permissions interface against TableSpec (or migrate the existing) and update the various io.deephaven.server.table.ops.GrpcTableOperation to plumb through the TableSpec execution logic.
