* update zig bindings to Zig 0.12.0
* support zig package manager
* Fix zig macos ci build
* Make the macos build use 1 process instead of hitting the macos
process limit immediately, utilize the build.zig `-Dparallel
false` option for macos ci
* Split the macos ci into a new build stage (out of the ubuntu,
macos build maxtrix), to allow for multiple architecture builds
in the future after the zig bindings improve
