build: use custom command to create single versiondef (#22290)

Browse Source 
When using a multi config generator, CMake generates an output file for
each configuration when using file(GENERATE). When the contents of the
file for each configuration are different, CMake fails. Instead, create
separate files for each configuration and add a build time step to copy
the configuration specific file to the generic path "auto/versiondef.h"
which is included at build time.
