Fix T80444: Triangle-Triangle intersection regression in 2.90

The problem is due to lack of precision with small and coplanar triangles.

Also, triangles that have vertices with the same coordinate are at the
threshold of the intersection.

We could add an epsilon to consider the minimum distance for intersection.

But that would add a lot of overhead to the code.

The solution used is to increase precision using doubles.
