Seth Hoenig 591394fb62 drivers: plumb hardware topology via grpc into drivers (#18504)
* drivers: plumb hardware topology via grpc into drivers

This PR swaps out the temporary use of detecting system hardware manually
in each driver for using the Client's detected topology by plumbing the
data over gRPC. This ensures that Client configuration is taken to account
consistently in all references to system topology.

* cr: use enum instead of bool for core grade

* cr: fix test slit tables to be possible
