CMake RelWithDebInfo builds failed on Windows because the Unified Runtime attempted to link with a Debug build of XPTI. Fortunately, the mismatch was detected by lld-link and it failed the build with the following error: error: /failifmismatch: mismatch detected for '_ITERATOR_DEBUG_LEVEL' The mismatch was due to a CMake generator expression in the Unified Runtime CMakeLists.txt that failed to account for RelWithDebInfo and MinSizeRel builds. Investigation of the above also resulted in the identification of an issue in the XPTI CMakeLists.txt file; use of `CMAKE_CXX_FLAGS_MINSIZEREL` for a RelWithDebInfo build and `CMAKE_CXX_FLAGS_RELWITHDEBINFO` for a MinSizeRel build.

…l#20078) CMake `RelWithDebInfo` builds failed on Windows because the Unified Runtime attempted to link with a `Debug` build of XPTI. Fortunately, the mismatch was detected by `lld-link` and it failed the build with the following error: `error: /failifmismatch: mismatch detected for '_ITERATOR_DEBUG_LEVEL'` The mismatch was due to a CMake generator expression in the Unified Runtime `CMakeLists.txt` that failed to account for `RelWithDebInfo` and `MinSizeRel` builds. Investigation of the above also resulted in the identification of an issue in the XPTI `CMakeLists.txt` file; use of `CMAKE_CXX_FLAGS_MINSIZEREL` for a `RelWithDebInfo` build and `CMAKE_CXX_FLAGS_RELWITHDEBINFO` for a `MinSizeRel` build.
