Annotate properties for KspTask

[msfjarvis]

Gradle 7.0 is making it an error to have properties in your Tasks without an @Input or @Output annotation, as noted here. This causes ksp-1.4.30-1.0.0-alpha05 to fail to run against Gradle 7.0-RC-1 with the following errors.

I was able to find the relevant code but lack knowledge of the codebase and Gradle itself to annotate these properties correctly.
