Subject: [PATCH] Fix missing `override` on XnnpackBackend destructor

Summary:
Add missing `override` keyword to `XnnpackBackend::~XnnpackBackend()`.

The destructor overrides a virtual base class destructor from
`BackendInterface` but was not marked `override`, which triggers
`-Werror,-Winconsistent-missing-destructor-override` on strict
toolchains (e.g. the ARVR toolchain on macOS).
