Proposal: Add new BufferAttribute methods

See original GitHub issue

Vector3 has these methods:

Vector3.applyMatrix3( matrix3 );
Vector3.applyNormalMatrix( matrix3 );
Vector3.applyMatrix4( matrix4 );
Vector3.transformDirection( matrix4 );

We need to be able to apply the same transforms to each element of a BufferAttribute.

I propose we add the following methods:

BufferAtribute.applyMatrix3( matrix3 );       // to replace Matrix3.applyToBufferAttribute()
BufferAtribute.applyNormalMatrix( matrix3 );  // new
BufferAtribute.applyMatrix4( matrix4 );       // to replace Matrix4.applyToBufferAttribute()
BufferAtribute.transformDirection( matrix4 ); // new

Suggestions for alternate APIs welcome.

Moving them to BufferAttribute sounds good to me. Was just trying to unify the last name.
