pw_system: Add synchronization to pw::System allocator

This global allocator was missing synchronization leading to heap
corruption as observed in b/352592037. In the future, this allocator
should be merged with our other global allocator, pw_malloc, as
detailed in b/352818465.

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/.
