Adds special treatment to Predef.classOf (#21523)

This is an updated PR of #20945, making the global initialization checker skips the analysis of `Predef.classOf` in scala2-library, since it is a stub method in tasty and is replaced by actual class representations in the backend. This prevents related warnings when running test_scala2_library_tasty. --------- Co-authored-by: EnzeXing <[email protected]>
