[roll third_party/pigweed] pw_build: Compile requirements for Python venvs
This change introduces a pip-tools workflow for compiling Python
package requirements and constraints for a pw_python_venv. This
produces a single requirements.txt file for installing all necessary
dependencies.
Using pip-tools enables a few additional features added in this CL:
- Adding hashes to the requirements.txt for package verification.
- A new optional GN subtarget for pw_python_venvs to download Python
packages locally.
- The pw_python_zip_with_setup template now takes a venv option and
will include third party python packages in the zip output. This
allows for fully offline installs of distributable bundles.
