Fix [#29556] shrinkwrap generates spikes if vertices fall exactly on the edge

bvhtree_ray_tri_intersection now using isect_ray_tri_epsilon_v3 with FLT_EPSILON. All devs I asked (incuding ones in physics/painting areas) were rather OK with this change, and better to do it now, with more than one month to detect regressions, if any!
