fix: resolve compile errors when feature optimism is on

[kien-rise]

Steps to verify

1. Go to crates/optimism/bin/Cargo.toml, enable feature optimism:

-default = ["jemalloc"]
+default = ["jemalloc", "optimism"]

2. Run cargo clippy or cargo build --package op-reth

Very nit but Reth actually uses nightly rustfmt with a specific rule to skip these dangling semicolons.

@kien-rise We should focus on block-building for the first pevm integration into RISE Stack so let's not base on this historical-sync branch. I meant to create a new branch without realizing the name conflict with this existing one...

So basically, let's try our best to not use a Reth fork in the RISE Stack. If we must, let's create a new branch with minimal changes to support the pevm block builder first.

Alright, will use this reth fork: https://github.com/risechain/reth/commits/pevm-integration/

Future PRs (if any) will target this branch (pevm-integration).

Note that the "minimal changes" is not so small. As long as we use our modified revm, the code changes on reth is inevitable.
