cmake: install zig to 'build_dir/stage3' during building

Browse Source 
This commit installs Zig to "build_dir/stage3" during building
so that distros' can easily find binary and use it for testing/etc.
This commit also splits "add_custom_target(stage3 ALL" and command that it invokes,
so that it won't retry it during installation,
as target will be considered not out-of-date.
