[host] Windows: Implemented service to launch LG as the SYSTEM user
Experimental, use at your own peril! This commit adds the ability for the LG host to install and launch with Windows as a system service. To install simply run `looking-glass-host.exe InstallService` or conversely to uninstall `looking-glass-host.exe UninstallService`.
