pw_build: Python package fixes

- Better error messaging when a python package can't be found.
- Sort pw_python_package listing in the generated requirements output.
- Switch the loop order when merging python packages as part of
  pw_create_python_source_tree. Before all package build output shared
  the same /tmp location which lead to problems if directories with
  the same name exist in multiple python packages. Now each
  python package gets its own /tmp build dir.
- Merge unique options.package_data entries that share the same
  package name. This prevents merged packages from clobbering
  eachothers entries.
- Add import error handling to pw_build_mcuxpresso. It is often run
  during gn gen stage when it may not be installed as a Python package.
- Remove python_dep on $dir_pw_protobuf_compiler/py for proto ._gen
  targets. This isn't required for running generate_protos.py and was
  propagating unnecessary deps.

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/.
