[roll third_party/pigweed] pw_libcxx: Add pw_libcxx library This provides a few symbols whose upstream implementation is unsuitable for embedded. Instead, we just implement these symbols by hand, which should just crash if they are ever reached.

Clone the repo
git clone https://pigweed.googlesource.com/pigweed/gonk
Source bootstrap.sh to download all compilers and tooling into the environment directory:
. ./bootstrap.sh
This should init all git submodules for you.
From here on the Pigweed environment is activated. You can activate the environment in a new shell without re-running bootstrap by sourcing activate.sh
. ./activate.sh
Build for the host and device by running:
pw build
This is mostly a shortcut with nice output for running gn gen out/gn and ninja -C out/gn.
The build commands are defined in: //tools/gonk_tools/build_project.py.
Run the host app and connect to it via pw-system-console:
./out/gn/host_device_simulator.speed_optimized/obj/applications/system_example/bin/system_example & \ pw-system-console --socket-addr default \ --proto-globs third_party/pigweed/pw_rpc/echo.proto ; \ killall system_example

Checkout the desired commits in each of these submodules:
third_party/stm32cube_f7/cmsis_core third_party/stm32cube_f7/cmsis_device third_party/stm32cube_f7/hal_driver
Then run from Gonk root:
python -m pw_stm32cube_build gen_file_list third_party/stm32cube_f7
