We need to modify spirv-tools existing CMakeLists.txt to make sure that its binaries and libs are not included in the filament installed output. This change was present before, but overwritten when spirv-tools updated (wrt the WebGPU project). In addition to modifying the CMakeLists.txt, we add a script to carry out the changes automatically when running the update script in the future. Fixes #9168
