Prevent memory context logging from sending log message to connected client.
When pg_log_backend_memory_contexts() is executed, the target backend
should use LOG_SERVER_ONLY to log its memory contexts, to prevent them
from being sent to its connected client regardless of client_min_messages.
But previously the backend unexpectedly used LOG to log the message
"logging memory contexts of PID %d" and it could be sent to the client.
This is a bug in memory context logging.
To fix the bug, this commit changes that message so that it's logged with
LOG_SERVER_ONLY.
Back-patch to v14 where pg_log_backend_memory_contexts() was added.
