[PATCH][CMake][OCaml] Add OCaml binding documentation to "all" target

[Alex Wang via llvm-commits]

Might as well keep the ALL version then, if that's alright.

A "flag" file of some sorts could work, I guess, but as you said earlier, that could be more work than its worth since the documentation builds fairly fast.
