Consider installing embedded Python on Windows

[ivmarkov]

Python is not installed by default on Windows, and overall, the installation is a hassle.
Therefore, the ESP-IDF installation script (PowerShell) for Windows installs an embedded Python instance in the ~/.espressif directory.

• We might do the same during the native cargo-first build when installing other stuff in the .espressif directory.
• We might even consider doing this for the PlatformIO build, even though it is not completely clear where exactly the Python instance should be uncompressed then (in ~/.platformio?).

I'd prefer if we would make this opt-in instead of opt-out, for example we could add a --install-python to the (yet to be created) cargo-espidf tool and cargo-pio tool for the people that really don't want to install python by themselves.
But tell me what you think.
