Re-land of bf1446791e.
Enable bundled Python CIPD packages in bleeding-edge mode. This
replaces the ZIP unpacking approach used before, and introduces
validation and management through the CIPD tool. The bleeding edge
version will only install if a sentinel file is present in the
"depot_tools" root; otherwise, default behavior will continue.
This method adds a upgrade and downgrade path to/from ZIP and
CIPD installations. This is done by rewriting the "win_tools.bat"
process:
1) Ensure that a bootstrap Python is present.
2) Use it to run "win_tools.py", which has the functionality of
"git_bootstrap.py" plus Python installation.
3) Run "win_tools.py" with appropriate flags.
Some tricks were employed to handle cases where there is an
already-running Python instance that uses the current Python
installation and executable. This happens on bots because the
system uses the same "depot_tools" checkout at multiple launch
layers. To this end, we use the "python.bat" as the "current Python"
authority and refrain from cleaning up old Python directories if their
"python.exe" binaries are currently in use.
We change the Git bleeding edge file to share the same
sentinel file as Python, ".bleeding_edge".
The new Python should have the same facilities as the original Python
bundle.
