Now we use upstream "test" step instead of separately calling all dependant steps, so that build system can now ran all of them paralelly. This means time spent in `src_test` is now significantly shorter. * "zig2" in both scenarios now has explicit target which is set by using zig-utils.eclass functions on a CBUILD/CHOST. This allows us to skip convertion logic in CMake and bootstrap.c, so that instead of patching them we can just update converter in zig-utils.eclass and unify target behaviour. * Disable autodocs generation for "std" module, since it can now be generated on-fly with `zig std` command.
