Fix ArgumentExpansion test expected results

Teach the ArgumentExpansion test to expect flattened lists as has always
been the case in the CMake language.  Now that the test should pass
enable the failure regex even when CMAKE_STRICT is not on.  Replace the
reference to the old ArgumentExpansion test behavior in the workaround
comment in cmMakefile::TryCompile with a full inline explanation.
