Guard Task execution via changed directories
The new Task in `.tekton/tasks/changed-dirs.yaml` produces a list of changed directories for a particular pull request as an array result. Given this result guards can be done, e.g. using CEL expressions to limit when a Task on the Pipeline needs to run. This way we can skip expensive Tasks that are unrelated to the change done in the pull request. Similar to work in #1188 and #524, with the distinction that the PipelineRun is executed, only potentially not in full.
