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.

Pigweed

Pigweed is an open source collection of embedded-targeted libraries–or as we like to call them, modules. These modules are building blocks and infrastructure that enable faster and more reliable development on small-footprint MMU-less 32-bit microcontrollers like the STMicroelectronics STM32L452 or the Nordic nRF52832.

For more information please see our website: https://pigweed.dev/.
