fix [#30529] BMesh: Wrong Indizes of Faces

problem was bow-tie quads would add opposite normals together and result in zero vector which was used for projection.
Now is_quad_convex_v3() checks if quad contains 2 faces which point away from eachother when split by either direction.

Theres another fix for this bug which can be done since creating the face can use existing edges in the example given so it wont have to guess which order of verts to use.
