Cycles: Remove the BVH cache feature

This removes the BVH cache feature from the UI, underlying code will be removed in a separate commit.

The BVH cache was added before we had a multi-threaded BVH build, and a lot of other optimizations were done since then, which makes this not useful anymore.

Fix T46162.
