dev: fixes post #1566

[tdelabro]

After the Blockifier rebase is merged a bunch of fixes and complementary features have to be developed

Full support for fees through STRK token #1571

• deploy the contract on genesis
• write tests allowing to pay with it

Remove generic hasher from block hash computation #1572

Respect the specs instead: https://docs.starknet.io/documentation/architecture_and_concepts/Network_Architecture/header/#block_hash Use pedersen hash

Return fee estimate that make sense #1573

The objects expected by the RPC are really different from those return in the TransactionExecutionInfo. And you guess correctly, there is no specification from Starkware on how to compute those. So let's use pathfinder impl as reference and copy/paste most of it: https://github.com/eqlabs/pathfinder/blob/main/crates/executor/src/estimate.rs#L12

Also add new fee fields to the block header

Use re_execute_transactions rather than simulate_transaction in prepare_tx_receipt #1576

re_execute allows us to rebuild the exact state, and therefore run the validate successfully (without it the nonce may not match or the account may not be funded, etc) using simulate with validate = false output lower fees that are supposed Most likely we can also compute the fees rather that reading it from the last event in the tx, which is a bit wacky

Add a pallet test for estimate_fee using simulation test #1575

It is now possible to skip the validation phase during estimate_fee. Write a check that uses it to validate an otherwise, invalid tx

Tx v3 tests #1574

Both successful and reverting
