pw_rpc: Add function for yielding the RPC lock in C++

Upcoming CLs will require threads to yield the RPC lock while waiting
for a different thread to finish executing an RPC callback.

- Add a config option for selecting how to yield (busy loop,
  pw::this_thread::sleep_for(), pw::this_thread::yield()).
- Add dependencies on pw_thread if backends are defined.
- Have the pw_rpc:disable_global_mutex config select the busy loop yield
  approach, since platforms with the mutex disabled either do not
  support threading or exclusively use RPC from one thread.
- Disable the RPC lock on a few platforms with no RTOS.

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.
