FindPython: Add cross-compilation support for Debian-based systems.
Debian-based Linux distributions locate their architecture-specific pythonX.Y-config tool at /usr/bin/<arch>-python<X.Y>-config
.
We first attempt to find and use the architecture-specific pythonX.Y-config tool. If the pythonX.Y-config tools are absent, then we proceed to find the architecture-specific Python libraries.
Fixes: #17912 (closed)
Topic-rename: FindPython-debian-cross-comp
