In EVM1 the SELFDESTRUCT is messy and complex due to the additional ETH transfer coupled with it.

1. Simplify selfDestruct by removing its address argument and do no transfer ether. The ether is destroyed with the account.
2. Add transfer() function that only transfers ether to other account. The target account's code is not executed. This function is needed to implement SELFDESTRUCT in evm2wasm.
