Restrict vcpkg dependencies to Windows platform and improve CMake module path handling

Add platform specifiers to all vcpkg dependencies and enable vulkan feature for ktx. Move CMAKE_MODULE_PATH configuration before project() call to ensure custom find modules are prioritized. Update all Find modules to use _find_package when available for better vcpkg integration. Add vcpkg CONFIG mode support to Findstb.cmake. Remove trailing whitespace.
