ProjectExplorer: Auto-detect installed GNU tools for ARM on Windows

Browse Source 
This patch implements the auto-detection for the installed
GCC embedded toolchains provided by "ARM Holdings":

https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads

The detection algorithm does search a toolchain path in a
Windows registry; this will work only if a toolchain was
installed using the installer.
