substrate-node: NativeElseWasmExecutor is no longer used (#2521)

This PR removes `NativeElseWasmExecutor` usage from substrate node.
Instead [`WasmExecutor<(sp_io::SubstrateHostFunctions,
sp_statement_store::runtime_api::HostFunctions)>`](https://github.com/paritytech/polkadot-sdk/blob/49a41ab3bb3f630c20e5b24cec8d92382404631c/substrate/bin/node/executor/src/lib.rs#L26)
is used.

Related to #2358.
