CMake: Make the default build empty

- Include subdirectories with EXCLUDE_FROM_ALL and make sure all targets
  have this property set. This gives external projects full control over
  what builds by default.
- Provide a `pw_apps` top-level group that builds standalone
  applications and add this to the CMake presubmit step.
