[roll third_party/pigweed] pw_log_rpc: Create Log RPC service & streams
An RpcLogStream matches a Multisink::Drain with an RPC writer and is
identified by the RPC channel ID. A persistent log stream can be created
by assigning an open writer to the RpcLogStream, or can be set when the
stream is inactive by the RPC Log service.
A map is provided to collect all log streams, persistent and dynamic. It
makes it easy to assign a writer to a log stream, or to flush all the
log streams.
Flushing is delegated to whatever owns the log stream map. Included is a
single thread, single Multisink::Listener that sequentially flushes the
log streams. Future work can make use of a work queue.
Test: sample app using raw strings log entries works with pw_console
calling:
```for payload in rpcs.pw.log.LogService.Listen.invoke():
for entry in payload.entries:
LOG.info("%s", entry.message)```
