Minor version string generation improvements.

Remove the KICAD_REPO_NAME option from the main cmake file and the
generated config.h file since it is no longer used.

Set the default branch name to "undefined" in CreateGitVersionHeader.cmake
instead of the KICAD_REPO_NAME option.

Remove generating KICAD_FULL_VERSION from CreateGitVersionHeader.cmake
and add it to WriteVersionHeader.cmake so that the default settings and
the new KiCadVersion.cmake definitions can be used to generate the full
version string as well.

Check to see if the branch name is set and only use the version to
generate the full version string.  This allows the use of the KiCad
version cmake file to create a version only string like "4.0.4" with
no trailing branch name.

Change build_version.cpp to use the full version string rather than
concatenating the version and branch strings.
