GHA/macos: tweak toolchain dump steps

- use documented flavour of `xcrun` option.

- show SDK version with a dedicated command.
  (Sometimes the SDK path is a symlink and doesn't tell the version.
  This is not at the moment the case in CI, but handle it anyway.)

- align group header with reality.
  Preinstalled vs. installed Homebrew packages can be recognized
  by their directory timestamps. Installed ones have a current date.

Closes #14434
