// Shim for ORT's core/common/common.h. Provides the small subset of
// macros that MLAS's q4_dq.cpp / q4common.h use: ORT_ENFORCE and ORT_THROW.
// Upstream's common.h pulls in logging, status, exceptions, and lots more
// — none of which MLAS itself needs. We map both macros to throwing
// std::runtime_error since MLAS is built without exception-disable in
// our CMake (see mlasi.h's MLAS_NO_EXCEPTION guard).
