Extract condition function to check the animation has initial value or not

 - Currently, gltf2-util.cpp uses long condition with comment to check the animation data contains initial value or not.
 - The comment has been essential to understand the purpose of the condition.
 - This patch extracts condition function to check it and uses proper naming instead of comment.
