refactor(handler): polish TxValidator API and add preset constructors

[rakita]

Summary

This PR polishes the TxValidator module for better usability, performance, and L2 integration support. The improvements were identified through multiple iterations of analysis focusing on:

1. API usability - Easy to use with minimal boilerplate
2. Performance - Low initialization overhead with Copy semantics
3. Configurability - Projects like op-revm and Tempo can reuse validation logic with configurable flows

Changes

API Improvements

• Add Copy derive to TxValidator and CallerFee for efficient passing
• Add preset constructors for common use cases:
  • for_deposit() - L2 deposit transactions (skips fees, balance, nonce)
  • for_tx_pool() - Transaction pool validation (stateless checks only)
  • for_block_builder() - Block builder with lenient checks
• Add composite GAS_FEES flag for all gas/fee related checks
• Add missing skip methods:
  • skip_tx_gas_limit_check()
  • skip_blob_fee_check()
  • skip_auth_list_check()
  • skip_max_initcode_size_check()
  • skip_caller_checks() (composite)
  • skip_gas_fee_checks() (composite)
• Add missing enable methods for ALL checks (symmetric with skip methods)
• Add query methods: has_any_checks(), has_all_checks(), enabled_checks()

Performance Improvements

• Add #[inline] annotations to all builder methods and validation hot paths
• Derive Copy to avoid unnecessary cloning

Tests

• Add tests for preset constructors
• Add tests for composite skip/enable methods
• Add tests for query methods
• Add test verifying TxValidator is Copy

Usage Examples

// L2 deposit transaction
let validator = TxValidator::for_deposit(SpecId::CANCUN)
    .with_chain_id(10);

// Transaction pool validation
let validator = TxValidator::for_tx_pool(SpecId::CANCUN)
    .with_chain_id(1)
    .with_base_fee(30_000_000_000);

// Custom configuration
let validator = TxValidator::new(SpecId::CANCUN)
    .skip_gas_fee_checks()
    .skip_caller_checks()
    .enable_chain_id_check();

Test plan

• cargo check -p revm-handler passes
• cargo test -p revm-handler -- tx_validation passes (12 tests)
