cmake: generated application version header when VERSION file is present

Browse source 
Allow applications to create a VERSION file in their application folder.

The presence of a VERSION file will create a app_version_h target which
generates an app_version.h file using same infrastructure as the Zephyr
kernel version.h generation.
