pw_multibuf: Replace Mutex with ISL Per-region mutexes have size overhead that is much larger than affordable for individual chunk regions. Prior to this change, SimpleAllocator's LinkedRegionTracker was 144 bytes (!) when compiled for host. After this change, it is 48 bytes (which is still too large, but now the size can be reasonably improved by reducing the number of pointer and size pairs).

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.
