Added EntryPoint v0.9 support for Account Abstraction (ERC-4337).

Features:

  • Added '0.9' to EntryPointVersion type
  • Added UserOperation<'0.9'> with new paymasterSignature field for parallelizable paymaster signing
  • Updated getUserOperationHash to support v0.9 (uses EIP-712 typed data like v0.8)
  • Updated toPackedUserOperation to handle paymasterSignature
  • Updated prepareUserOperation type definitions for v0.9
