chore(l2): rename L1Watcher's get_logs and process_logs functions (#3189)

**Motivation**
The L1Watcher's `get_logs` and `process_logs` function names are
misleading, as they only handle **deposit** logs, not all logs.

**Description**
Renames `get_logs` to `get_deposit_logs`, and `process_logs` to
`process_deposit_logs` for clarity.
