feat: implement eth_get_transaction_count

[enitrat]

kakarot-ssj/crates/contracts/src/kakarot_core/eth_rpc.cairo

Lines 128 to 130 in b1f7f8c

	fn eth_get_transaction_count(self: @TContractState, address: EthAddress) -> u64 {
	panic!("unimplemented")
	}

Given an evm address, this will return the transaction count (none) of this address.

Use it where required in the codebase, for example:

kakarot-ssj/crates/evm/src/backend/validation.cairo

Lines 35 to 38 in b1f7f8c

	// Validate nonce
	let starknet_caller_address = get_caller_address();
	let account = IAccountDispatcher { contract_address: starknet_caller_address };
	assert(account.get_nonce() == tx.nonce(), 'Invalid nonce');

Hi, I am Cairo Developer with lots of experience contributing to Cairo projects, you can check my profile to be sure of this.

How I plan on tackling this issue

I would go through the code base and understand what is needed and ensure I do just that, after that I would write a robust test ensuring all test cases are covered and the feat behaves as expected.
