dev-lang/zig: sync 9999 with 0.13.0-r2
* Update to use zig-utils and zig eclasses instead of local get_zig_mcpu etc. functions. * "stage3" compilation is unified by combining build.zig options, now both cmake (+llvm) and bootstrap.c (-llvm) build up to "zig2" target, after that we use zig.eclass with common options. * Before migrating to the zig.eclass, test steps in src_test have been ran sequentially in for-loop, which allowed logic inside each step to ran parallelly but not several steps at a time. 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.
