LOG: [clang] Migrate away from PointerUnion::dyn_cast (NFC) (#232179)

Note that PointerUnion::dyn_cast has been soft deprecated in
PointerUnion.h:

    // FIXME: Replace the uses of is(), get() and dyn_cast() with
    //        isa<T>, cast<T> and the llvm::dyn_cast<T>

Literal migration would result in dyn_cast_if_present (see the
definition of PointerUnion::dyn_cast), but this patch uses dyn_cast.
Note that loadAPINotes() returns false only after storing a nonnull
APINotesReader * in Readers[*Dir].
