LOG: Update test for C++20 defaulting compilers after #173236 changed the expected diagnostic message. (#174377)

Change #173236 changed the emitted error message which caused the test
`clang/test/SemaCXX/typeid.cpp` to fail if tested with a compiler that
defaults to C++20 because the error message has changed. This change
updates the test to expect the correct error message depending on
whether the compiler defaults to C++20 or earlier.
