Subject: [PATCH] Extract FML command_line target (#26028)

Command-line argument parsing is valuable even in the absence of the
rest of FML's functionality.

This is pre-factoring for uwptool, which adds an adb-like helper tool
for install, uninstall, and launch of UWP applications for Windows
platforms.
