New method to access ProviderSectors HAMT from market actor

[LexLuthr]

We need a way to access information in https://github.com/filecoin-project/go-state-types/blob/ad909a3d6ebef5ebc5688b4310e954e27da2203b/builtin/v13/market/market_state.go#L66. This can be very useful to verify F05 deals post NV23 if sealer is using ProveCommitSector3 method to commit all sectors.

We should have 2 methods:

1. a list of all sectors[deals] per provider/miner
2. querying specific deal in a specific sector of a miner.

@LexLuthr I've moved this to the lotus repo as the API is going to have to be here rather than in go-state-types.

Thank you. Look forward to have this soon. Along with #11936, we will have all we need to track market deal reliably.
