  [Matrix] Add -debug-only prints when matrices get flattened (#142078)

This is a potential source of overhead, which we might be able to alleviate in some cases. For example, static element extracts, or shuffles that pluck out a specific row. Since these diagnostics are highly specific to the pass itself and not immediately actionable for compiler users, these prints don't make a whole lot of sense as Remarks.
