Add additional benchmarks to picking::ray_mesh_intersection

[BD103]

In order to merge #18232 (originally #16148), the improvements to our benchmarks had to be reverted in order to avoid merge conflicts. These changes are still generally useful, however, and would improve our picking benchmarks if integrated.

Specifically, changes changes made to ray_mesh_intersection.rs here need to be combined with the changes made in #17033, which caused the merge conflict.
