Replace FetchContent_Populate by FetchContent_MakeAvailable (#4310)

```bash
  CMake Warning (dev) at C:/Users/vagrant/AppData/Local/Temp/pip-build-env-blxl_9th/overlay/Lib/site-packages/cmake/data/share/cmake-4.0/Modules/FetchContent.cmake:1953 (message):
    Calling FetchContent_Populate(spirv-llvm-translator) is deprecated, call
    FetchContent_MakeAvailable(spirv-llvm-translator) instead.  Policy CMP0169
    can be set to OLD to allow FetchContent_Populate(spirv-llvm-translator) to
    be called directly for now, but the ability to call it with declared
    details will be removed completely in a future version.
```
