[extensionauthtest] Remove extensionauthtest.MockClient (#12567)
<!--Ex. Fixing a bug - Describe the bug and how this fixes the issue. Ex. Adding a feature - Explain what this achieves.--> #### Description Removes `extensionauthtest.MockClient`. Users can use either `extensionauth.NewClient` or use `extensionauthtest.NewErrorClient` as a convenience method to replicate the `MustError` field behavior. Doing a Github search, I am unable to find usages of this outside of contrib, which I dealt with on PR open-telemetry/opentelemetry-collector-contrib/pull/38401, thus I believe this should be fine to remove in one go.
