shiboken: Use enum values from Clang

Remove a lot of ugly value parsing code in favor of
clang_getEnumConstantDeclValue() and
clang_getEnumConstantDeclUnsignedValue() depending on the
type.

Introduce a class EnumValue containing a union of qint64 and quint64 values
to represent signed/unsigned values correctly and use that in the code model
and meta language classes.
