Improve handling of explicit C++ dialect requests in the following scenarios:
1. Fail immediately when a user explicitly requests a C++ dialect which the compiler fails
to satisfy instead of silently deleting the compiler.
2. Fix handling of old C++ dialects, e.g. --with-cxx-dialect=c++[03|98]. If the user
explicitly requests these versions a hard error is produced. Previously the C++ compiler
would be silently deleted.
3. Fix handling of unsupported C++ dialects, e.g. --with-cxx-dialect=c++2b. Instead of
crashing configure, these are now correctly diagnosed as "Unknown C++ dialect".
Address the following additional C++ dialect errors. In all cases configure will now
produce an immediate error in checkCxxDialect():
1. --with-cxx=<does not work with C++11>
2. --downlod-package --with-cxx=<does not work with package C++ requirement>
3. --download-package (but implicit compiler does not support package min dialect).
