Fix T42630: Triangulate returns invalid face-map
...
Triangulate with beautify caused a bug when there were existing edges
could make the bmesh-operator return an invalid face-map.
Now the beauty is calculated on the 2d-tri's resulting from polyfill,
its simpler and faster.

- selecting 3 verts would use the first selected edge as the tangent (now use longest).
- selecting 1 vert betweem edges, uses the edges to define the tangent.

Fix T40297: Crash while ripping an edge when autosmooth is activated.
...
Turned out there was still quite a few cases were indices were set dirty,
but elem_index_dirty was not tagged accordingly (mostly for BM_LOOP,
but a few others as well). So probably this crash was not the only one
hidden here.
Hopefully all possible cases were catched this time!

Fix T40162: Vert connect creates extra face cutting across concave NGon.

This commit disallows cuts across faces where the same vertices can create better cuts on different faces.

Triangulate Modifier: using different ngon and quad methods
...
Quads: Beauty, Fixed, Fixed Alternate, Shortest Diagonal
Ngons: Beauty, Scanfill

after Clt+T
