[graphql] split out epoch fields into new sui system state type (#14163)

## Description 

On jsonrpc we can (only) query for latest sui system state. The initial
graphql draft schema combines sui system state to the epoch struct, but
since not all sui system state data are stable for the epoch, this draft
proposes splitting out most of the epoch into a new sui system state
type.
1. Query has new resolver latest_sui_system_state
2. validator type can now resolve operation_cap, staking_pool, and
exchange_rates to move objects
3. protocol config typing is modified to take in a ProtocolConfig
instead of fetching the same data source for each of its fields

## Test Plan 

How did you test the new or updated feature?
