libmetal: cmake: support machine less build

Browse Source 
libmetal can be build without any machine support. It is possible that
vendors implement machine specific interfaces outside of libmetal and
link it with demos during build time. Hence, remove requirement to have
MACHINE and PROJECT_MACHINE variables from the build system. If vendor
prefer to choose 'template' machine, they can pass such option during
cmake configuration.
