Add `unchecked_disjoint_bitor` per ACP373

Following the names from libs-api in https://github.com/rust-lang/libs-team/issues/373#issuecomment-2085686057

Includes a fallback implementation so this doesn't have to update cg_clif or cg_gcc, and overrides it in cg_llvm to use `or disjoint`, which [is available in LLVM 18](https://releases.llvm.org/18.1.0/docs/LangRef.html#or-instruction) so hopefully we don't need any version checks.
