pw_rpc: Allow simultaneous calls to one method

Calls already include a call_id that, prior to this CL, was largely
unused. This CL looks up calls based on their ID and uses it to
allow multiple outstanding calls on the same channel+service+method
at once.

Note that we still use all of channel+service+method+call to look
up the record of a given call, even though existing clients should
use IDs only once across a channel (so channel+call IDs would be
enough). In the future, this may be relaxed in order to allow
omitting service+method IDs in response messages.
