feat(forge): add createWallet() cheat code for new Wallet struct (foundry-rs#5332)

* chore: add Wallet struct and other relevant functions to 'HEVM.sol'

* feat: add 'HEVMCalls::GetNonce0' to env utils for Wallet, rename 'GetNonce' to 'GetNonce1'

* feat: add CreateWallet/Sign to HEVM match in cheat utils

* chore: add Wallet struct and other relevant functions to 'Cheats.sol'

* test: add tests for 'createWallet' in Wallet.t.sol

* test: add tests for getNonce/sign in Wallet.t.sol

* chore: remove 'unwrap' after 'create_wallet' calls

* style: forge fmt 'testdata/cheats/Wallet.t.sol'

* test: add x & y to addr check to Wallet.t.sol

* chore: rename 'cheats' to 'vm' in Wallet.t.sol

* test: change pkSeed to uint256 to check whole private key range

* Add 'bound' func, remove 'vm.assume(pk != 0)'

* docs: add doc comments surrounding 'create_wallet'
