build: Simplify build infrastructure for command line tools (#613)

Provide a build convention plugin for command line tools, and use
`libs.versions.toml` for command line tool dependencies. Adjust the
individual tool `build.gradle.kts` files accordingly.

Remove unnecessary `gradle.properties` and `settings.gradle` files for
projects that are included as subprojects, not included builds.

Add a trivial test for each command line tool so there are tests to run
and provide some confidence that automated library upgrades don't break
command line tool compilation.
