cmake: Set the PW_ROOT env variable in pigweed.cmake

Instead of setting the PW_ROOT environment variable inside of the
root CMakeLists.txt, it is set if if needed through
pw_build/pigweed.cmake.

In addition, the provided toolchain files are updated to use the
relative path to ../../pw_build/pigweed.cmake to ensure they work
in environments which are not bootstraped.

This ensures that both the upstream toolchains and Pigweed's
CMake tooling in general can be used outside of a bootstrapped
environment.

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.
