fix: state alias, test and game versions from code

An alias carries the version of the profile it aliases (version_basis
kind alias): mednafen_saturn and mednafen_vb read v1.32.1 and v1.31.0,
the mupen64plus_next builds 2.6.0, flycast_gles2 the flycast tag form.
The libretro-samples test cores without a pin take the commit their
profiled_date names and read library_version there.
