### Summary  
<!-- Briefly describe the new feature -->  
This pull request introduces changes to standardize macOS builds by
adopting the "universal2" architecture, which supports both `arm64` and
`x86_64`. The updates simplify the build process, ensure consistency
across tools, and improve compatibility. Key changes include
modifications to the CMake configuration, build scripts, and Python
packaging setup.

### macOS Build Standardization:

*
[`mssql_python/pybind/CMakeLists.txt`](diffhunk://#diff-dbb5892fbbb28149d1639664797cf3adb48ced28ec11aba95f2e2b338ca46badL31-R32):
Replaced architecture-specific logic with a universal2 configuration for
macOS, setting `ARCHITECTURE` to "universal2" and ensuring
`CMAKE_OSX_ARCHITECTURES` is set to `arm64;x86_64`. Updated `WHEEL_ARCH`
to "universal2" for macOS builds.

Simplified the macOS build script by removing architecture-specific
handling and ensuring the build process defaults to creating universal2
binaries. Added diagnostics to verify the resulting binary.

### Python Packaging Updates:

*
[`setup.py`](diffhunk://#diff-60f61ab7a8d1910d86d9fda2261620314edcae5894d5aaa236b821c7256badd7L41-R44):
Updated macOS-specific logic to always use the "universal2" platform tag
(`macosx_15_0_universal2`) for wheel packaging. Removed architecture
detection and replaced it with a unified configuration.

These changes streamline the macOS build process, reduce complexity, and
ensure compatibility with both Apple Silicon and Intel-based Macs.
