Vendoring wheels has three benefits: * There's far less files, so Firefox checkouts will be smaller. * It works around `zipp` not allowing `pip install` from extracted source `tar.gz` files. Now, we should be able to use the pip resolver against vendored packages, which will be needed for future mach virtualenv work. * `./mach vendor python` takes far less time to execute. Since we need the raw Python to be available to add to the `sys.path`, we extract the wheels before putting them in tree. Due to the structure of some wheels being less nested than of a source `tar.gz`, `common_virtualenv_packages` needed to be adjusted accordingly. `install_pip_package()` had to be tweaked as well since you can't `pip install` an extracted wheel. So, we "re-bundle" the wheel before installing from a vendored package. Replace python packages with wheels where possible This contains the vendoring changes caused by the last patch. For reviewing, there's a couple things to note: * A bunch of files are deleted, since there's generally less files in a wheel than in a source archive. * There's a new `.dist-info` directory for each extracted wheel, so expect roughly 5 or 6 new files for each wheel'd package. * There should be no source code changes other than moves from package names changing from having `-` to having `_`.
