refactor(executor): thread local instead of global variable

[KaoImin]

What this PR does / why we need it:

This PR：
Divide the global variable of system contract roots (header cell root and metadata root) into two parts:

1. Two thread local storage that use in the exec() function. The local keys are loaded at the start of execution, and the life cycle is the exec() function. It is use for transactions execution. It is use for transactions executions.
2. Other using the system contract roots places change to get them from the DB as following:

let state_root = self.storage.get_latest_block_header(ctx).await?.state_root;
let backend = AxonExecutorAdapter::from_root(
    state_root,
    Arc::clone(&self.trie_db),
    Arc::clone(&self.storage),
    Default::default(),
)?;
let root = backend.get_metadata_root();
let metadata_handle = MetadataHandle::new(root);
...
