CMake build options improvements

[walbourn]

This updates the use of CMake build options to address a few issues:

• For VCPKG port, I want to add more features to control use of XInput vs. GameInput vs. WGI

• For cases where you are building for Windows 10 or later, the default logic will try to use WGI for input. This causes link issues when the library was built for Windows 10, but the client wasn't or vice-versa. This ensures the expected build define is in the CMake targets--MSBuild targets still have to deal with this manually.

• GameInput supports MinGW64, and otherwise can only use XInput.

• This also includes some cleanup of the CMake logic.

Pull Request Overview

This PR refactors the build configuration logic for MinGW and other platforms to properly manage the BUILD_XINPUT flag and simplify XAudio configuration. The changes consolidate platform-specific build settings and add new MinGW presets with GameInput support.

• Moved platform-specific configuration logic earlier in CMakeLists.txt for better organization
• Removed redundant BUILD_XINPUT flag from the XAudio2Redist preset in CMakePresets.json
• Added new MinGW presets with GameInput support
