qmath.h: clean up inclusions

Browse Source 
We can remove some preprocessor provisions around #include <cmath>:
they're ineffective because <cmath> is actually already included
indirectly (qmath.h -> qglobal.h -> qnumeric.h -> cmath).

Leave the inclusion to honor IWYU, but remove the defines around
it as they're apparently not necessary at all.

While at it, explicitly include qnumeric.h because it's used (for
instance, the qIs* fp classification functions called by qmath.h are
declared in qnumeric.h).
