core: move compiler defines from base.hpp into cvdef.h
Steps to reproduce
Compile cpp file that includes "opencv2/core/cvdef.h"
Error :

Potential fix - add namespace cv around template declaration
namespace cv {
template <bool x> struct CV_StaticAssert_failed;
template <> struct CV_StaticAssert_failed<true> { enum { val = 1 }; };
template<int x> struct CV_StaticAssert_test {};
};
