[clang][deps] Serialize JSON without creating intermediate objects (#111734)

The dependency scanner uses the `llvm::json` library for outputting the
dependency information. Until now, it created an in-memory
representation of the dependency graph using the `llvm::json::Object`
hierarchy. This not only creates unnecessary copies of the data, but
also forces lexicographical ordering of attributes in the output, both
of which I'd like to avoid. This patch adopts the `llvm::json::OStream`
API instead and reorders the attribute printing logic such that the
existing lexicographical ordering is preserved (for now).
