[roll third_party/pigweed] pw_rpc: Support legacy unsolicited responses
When concurrent request support was first implemented, a sentinel
value (kOpenCallId) was used as the call ID for unsolicted responses.
Servers built after that change send "open" responses with call ID
kOpenCallId. Clients built after that change accepted "open" responses
with only that call ID.
This resulted in a failure when an up-to-date client communicates with a
legacy server: the server will send an unsolicted ("open") response with
call ID zero, but the client expects unsolicted responses to have call
ID kOpenCallId.
After this commit, clients will accept unsolicted responses with call
IDs of either zero of kOpenCallId.
Fix: b/325304606
