Generating the list of all modules in library.zip and publishing that as an appveyor artifact

Issue #15886 raises the problem of python environment maintenance between nvda core & add-ons. How much responsibility does NV Access take to provide the environment that add-on developers need to build their code, and thus avoid the developer having to roll their own and coming up against version incompatibilities, dependency chain issues, architecture compatibility issues, etc.

In order for NV Access to manage this issue more effectively, a first step is to clearly list the Python standard library modules included in nvda's binary builds.

Describe the solution you'd like

• In the build system, after building NVDA with scons, recursively find all *.pyc files in the generated library.zip
• Write them all to a file, converting their paths to Python module syntax, I.e. from x\y\z.pyc to x.y.z.
• Make sure that file is exported as an artifact.

Then at a later stage, we can look at producing diffs of this file between releases.
