meson: cache get_target_generated_dir
This reduces the build time about 2 sec. The result itself is not hard
to calculate. However, persistent join calls with the same 2 strings are
not that usefull. This also caused about 600'000 calls to
get_target_dir, we are now down to 60'000 calls form this function to
get_target_dir.
