Allow using the GetVersion.cmake file for any platform

Changes GetVersion.cmake to allow use by platforms other than generic_unix, by allowing the cmake
include of version.cmake before including GetVersion.cmake on other platforms.

Fix version reporting for ESP32 builds when executing mkimage.sh by including the
AtomVM/version.cmake and AtomVM/CMakeModules/GetVersion.cmake files to be able to get the correct
version number when reporting build information during build/mkimage.sh execution.
