0025574: gp_YawPitchRoll Euler Angle computation gives wrong results

Browse Source 
Conversion of gp_Quaternion to and from intrinsic Tait-Bryan angles (including gp_YawPitchRoll) is fixed.

Before that fix the sequence of rotation axes was opposite to intended; e.g. gp_YawPitchRoll (equivalent to gp_Intrinsic_ZYX) actually was defining intrinsic rotations around X, then Y, then Z.
Now this is fixed, and rotations are made in correct order.

Comments to gp_EulerSequence enumeration are restored (lost due to CDL extraction).

Test bugs fclasses bug25574 is added to check correctness of Euler sequences, including cases from #25574 and #25946.

@subsection Correction of interpretation of Euler angles in gp_Quaternion
Conversion of gp_Quaternion to and from intrinsic Tait-Bryan angles (including gp_YawPitchRoll) is fixed.
Before that fix the sequence of rotation axes was opposite to intended; e.g. gp_YawPitchRoll (equivalent to gp_Intrinsic_ZYX) actually was defining intrinsic rotations around X, then Y, then Z.
Now this is fixed, and rotations are made in correct order.
Applications that use gp_Quaternion to convert Yaw-Pitch-Roll angles (or other intrinsic Tait-Bryan sequences) may need to be updated to take this change into account.
