Maker: add build.zig.zon files to configuration cache manifest

closes #36255

follow-up enhancement: only add the root build.zig.zon file as an input
to the cache manifest. Do a cache check *before* fetching, that has the
ability to skip fetching. If fetching needs to be run, then add the
build.zig.zon files as discovered files, keeping the stat and contents
around from the fetch process rather than redundantly doing the file
system operations.
