We now only use PHIVE for those tools that are not compatible
with the PHP versions we currently support (7.2-7.4).
This currently is only the PHP copy-paste detector
(which requires PHP >= 7.3).
This also (as a nice side effect) provides `ddev composer normalize`
out of the box.
For YAML linting, we now use the `symfony/yaml` package (which already
was installed as an indirected dependency, and which we now explicitly
require).

PhpStorm by default indexes `*.phar` files. For our current set of
tools, we do not want this. (This keeps PhpStorm from complaining
about multiple versions of the same class.)
Also mark the tools as binary for git.
