0024945: Extrema_ExtPElC::Perform does not consider angular tolerance when calculates angle between two vectors

Browse Source 
Consider angular tolerance during calculation of angle between two vectors for protection against deviations that are significantly less than tolerance.
Simplified code to reduce number of comparison
Added QA command OCC24945 and test case bugs/moddata_3/bug24945
