validator: ditch call to old faucet test api in solana test validator (#8068)

The solana-test-validator in validator package calls old faucet test api, which we want to deprecate in #7912
In this PR, solana-test-validator spawn local faucet directly, omitting the (deprecated soon) faucet test helper function.
