EVM: emit event log when native token withdrawal is applied

What

This MR introduces a new kernel EVM event that is emitted by the withdrawal precompile upon successful execution.

Why

Currently there's no easy way to track withdrawal status along the way from L2 to L1, partially because of how the delayed outbox works.
This MR fixes that, and also allows to use the same indexer & frontend for both native token and FA bridges.

How

Withdrawal precompile now adds special event to the execution outcome logs, which contains:

• Sender: L2 account that initiated the withdrawal)
• Receiver: final destination on L1
• Amount: in wei, before conversion to mutez
• Withdrawal ID: nonce (counter) that is incremented on every successful or failed withdrawal (also both for native and FA tokens)
