vtkTestingInteractor: Change ErrorThreshold to 0.05
Upon the introduction of the new image testing framework, this variable should have changed like the default threshold of vtkRegressionTestImage changed.
- Several tests' baselines have been updated because they should had been updated in the past but they were not.
- Several classes have been fixed since recent changes caused related tests to fail.
- Several tests have been excluded because their failures could not explained and their baselines should not be updated.
This MR resolves #19206 (closed).
