Best reviewed one commit at a time. The first commit is stolen from #101014, and we should probably let that PR merge before this one.

It's now much more like the `-Zhir-stats` output. - Each line is preceded with `meta-stats`, which makes the provenance clearer and allows filtering of the output. - Sections are now sorted in reverse order of size. - Column headings avoid the need to repeat the word "bytes" on every line. - Long numbers now have `_` separators for easier reading. - Consistent use of '-' within section labels, rather than a mix of '-', '_', and ' '. The code itself is shorter and easier to read thanks to: - the `stat` macro, which encapsulates each section's encoding, avoids some boilerplate, and removes the need for some low-value comments; - the `stats` vector, which replaces dozens of local variables.
