Make NodeClient satisfy AptosRpcClient interface

[friedemannf]

Description

The AptosRpcClient interface is supposed to be implemented by NodeClient:

// AptosRpcClient is an interface for all functionality on the Client that is Node RPC related. Its main implementation
// is [NodeClient]

But doesn't actually satisfy the interface due to two methods:

1. NodeAPIHealthCheck

methods are missing: NodeAPIHealthCheck(durationSecs ...uint64) (api. HealthCheckResponse, error)

I wasn't sure if you'd want to break compatibility by renaming the method and added a new method NodeAPIHealthCheck and kept the old one NodeHealthCheck while marking it as deprecated.

2. BuildSignAndSubmitTransaction

need the method: BuildSignAndSubmitTransaction(sender *Account, payload TransactionPayload, options ...any) (data *api. SubmitTransactionResponse, err error)
have the method: BuildSignAndSubmitTransaction(sender TransactionSigner, payload TransactionPayload, options ...any) (data *api. SubmitTransactionResponse, err error)

NodeClient already accepted the TransactionSigner interface and I lifted its usage to the AptosRpcClient interface. This should not break compatibility as *Account can still be passed.

Test Plan

Ran all tests with go test ./...
