Remove transmutation of persistent executor

[mversic]

Currently WasmCache stores &'world mut StateTransaction<'block, 'state> inside. We create WasmCache before obtaining any StateTransaction, so the first problem is that there is no 'world lifetime when we create WasmCache.

I tried to eliminate 'world lifetime by storing Arc<RefCell<StateTransaction<'block, 'state>>> inside WasmCache. In this case problem will be in categorize_transactions function. Basically:

fn categorize_transactions<'block, 'state>(
    transactions: Vec<AcceptedTransaction>,
    state_block: &'block mut StateBlock<'state>,
) -> Vec<CommittedTransaction> {
    let wasm_cache: WasmCache<'block, 'state> = WasmCache::new();
    validate(tx1, state_block, &mut wasm_cache);
    validate(tx2, state_block, &mut wasm_cache);  // here borrow check error
    ...
}

fn validate(
    tx: AcceptedTransaction,
    state_block: &'block mut StateBlock<'state>,
    wasm_cache: &mut WasmCache<'block, 'state>,
) {
    ...
}

&mut WasmCache<'block, 'state> is invariant over 'block thus calling validate multiple times will fail borrow check

I concluded that the current approach is the best:
since Store<T> instantiates and owns Instance, the only way to handle numerous T (corresponds to a transaction) while keeping a single Instance would be to have a comprehensive T (i.e. Option<CommonState<WithMut<'txn, 'block, 'base>, Validate<SignedTransaction>>>) and replace it transmuting about lifetimes (i.e. 'txn)
