Remove ScriptLoader from script_runner_test.cc

This CL removes MockScriptLoader definition,
migrates MockScriptLoader::Create*() to MockPendingScript, and
makes ScriptLoader final.

Other changes to test bodies are mechanical:
- Replaced script_loader with pending_script,
- Replaced ScriptLoader with PendingScript,
- Remove "->GetPendingScriptIfControlledByScriptRunner()",
