opt_mem, memory_*: Refuse to operate in presence of processes

Processes can contain `MemWriteAction` entries which are invisible to
most passes operating on memories but which will be lowered to write
ports later on by `proc_memwr`. For that reason we can get corrupted
RTLIL if we sequence the memory passes before `proc`. Address that by
making the affected memory passes ignore modules with processes.
