Subject: [PATCH] revive-runner: enable PVM logs (#442)

This PR fixes a small oversight from #431: Set the debug config of the
revive-runner `Runtime` such that we get the PVM logs back. Since the
revive runner runtime is mainly meant for debugging, I further decided
to enable unlimited contract sizes and disable [EIP
3607](https://eips.ethereum.org/EIPS/eip-3607) too.

 - The supported `polkadot-sdk` release is `unstable2507`.
 - The `INVALID` opcode and OOB memory accesses now consume all remaining gas.
 - Emit the `call_evm` and `delegate_call_evm` syscalls for contract calls.
+- The `revive-runner` can execute arbitrarily large contract blobs.
 
 ### Fixed:
 - The missing `STOP` instruction at the end of `code` blocks.
