[trusted task] Verify task and pipeline when apply them about experimental HOT 4 CLOSED

Yep! The key points of this issue is to understand the code in
https://github.com/tektoncd/experimental/blob/main/pipeline/trusted-resources/pkg/trustedtask/trustedtaskrun.go
https://github.com/tektoncd/experimental/blob/main/pipeline/trusted-resources/pkg/trustedtask/trustedpipelinerun.go
In these two files we verify the task and pipeline from taskrun and pipelinerun.

This issue want to have 2 similar files: trustedtask.go and trustedpipeline.go
and then create TrustedTask and TrustedPipeline, to do similar work for verification.
