ExternalProject: Propagate the generator platform

When the CMAKE_GENERATOR option is given to ExternalProject_Add, look
also for option CMAKE_GENERATOR_PLATFORM to pass on to cmake as a cache
definition.  When no CMAKE_GENERATOR option is given explicitly then use
the current project's CMAKE_GENERATOR_PLATFORM (since we already use its
CMAKE_GENERATOR).
