Merge #150482

150482: rpc: authorize DRPC method endpoints for tenants for split Internal service r=cthumuluru-crdb a=shubhamdhama

Previously, we had a single Internal service with many RPC methods. As part of the work in #148726, this service was split into several specialized services (KVBatch, TenantService, RangeFeed, TenantUsage, TenantSpanConfig). This change will allow the upcoming DRPC authorization interceptors to authorize access to these newly split service endpoints.

Release note: none
