[ValueTracking] Add support for `xor`/`disjoint or` in `isKnownNonZero`
Handles cases like `X ^ Y == X` / `X disjoint| Y == X`.
Both of these cases have identical logic to the existing `add` case,
so just converting the `add` code to a more general helper.
Proofs: https://alive2.llvm.org/ce/z/Htm7pe
Closes #87706
