QTextFormat: use qHash(double/float) instead of own implementation

The implementation of hash(float) does not treat +0 and -0 the same,
thus violating the property required of hash functions that they
produce equal hash values for equal input.

Simply use the qHash() FP functions which recently became available
and which do not have that problem.

This was found by unrelated code review. I'm not aware of any user-
visible issue this fixes.
