The `macro` directory contains most of the macro tests, but not all of them; move the remainder into `macro`.

As with the list of builtin macros, use tidy to make sure the list of builtin attributes stays sorted.

Most macro tests use `macro` in the name, making it easy to find and run tests relevant to macros. However, a few use `mbe` instead. Rename those to say `macro`.

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
