ENH: Support more preprocessor values in VS6

Previously we rejected all preprocessor definition values containing
spaces for the VS6 IDE generator.  In fact VS6 does support spaces but
not in combination with '"', '$', or ';', and only if we use the sytnax
'-DNAME="value with spaces"' instead of '-D"NAME=value with spaces"'.
Now we support all definition values that do not have one of these
invalid pairs.  See issue #8779.
