FetchContent_Populate is deprecated

[vinser52]

The following Cmake warning occurs during the build of UMF:

CMake Warning (dev) at /usr/share/cmake-3.30/Modules/FetchContent.cmake:1953 (message):
  Calling FetchContent_Populate(level-zero-loader) is deprecated, call
  FetchContent_MakeAvailable(level-zero-loader) instead.  Policy CMP0169 can
  be set to OLD to allow FetchContent_Populate(level-zero-loader) to be
  called directly for now, but the ability to call it with declared details
  will be removed completely in a future version.
Call Stack (most recent call first):
  src/CMakeLists.txt:38 (FetchContent_Populate)
This warning is for project developers.  Use -Wno-dev to suppress it.

The cmake files should be updated to use FetchContent_MakeAvailable instead of FetchContent_Populate.
