Introduce a new simulated backend implementation under ethclient/simulated and migrate bind-facing wrappers/tests to use it.
Key changes:
- Add the new backend entry points and behavior in ethclient/simulated, including chain control helpers used by tests (commit/rollback/fork/time adjustment).
- Update legacy bind wrappers in accounts/abi/bind/backends to delegate to the new simulated backend while preserving old APIs.
- Align bind v2/backend and utility tests to the new simulated backend client surface and transaction flow.
- Refresh abigen/bind tests and shared interfaces impacted by the backend migration.
Compatibility notes:
- Keep backward-compatible wrapper constructors for existing contract test code.
- Preserve legacy transaction paths in tests while supporting EIP-1559-aware flows where applicable.
Validation:
- Verified affected packages compile and pass tests.
- Verified repository-wide go test ./... passes after follow-up compatibility fixes.
Adds ethclient support for the eth_simulateV1 RPC method, which allows
simulating transactions on top of a base state without making changes to
the blockchain.

Some chains’ network IDs use hexadecimal such as Optimism ("0xa" instead
of "10"), so when converting the string to big.Int, we cannot specify
base 10; otherwise, it will encounter errors with hexadecimal network
IDs.

* eth/filters, ethclient/gethclient: add fullTx option to pending tx filter #25186
This PR adds a way to subscribe to the _full_ pending transactions, as opposed to just being notified about hashes.
In use cases where client subscribes to newPendingTransactions and gets txhashes only to then request the actual transaction, the caller can now shortcut that flow and obtain the transactions directly.
