DXVK-Remix build fails due to missing meson.build files

Description

DXVK-Remix build fails due to nonexistent build file tests/rtx\dxvk_rt_testing\meson.build. If you delete the dxvk_rt_testing directory, sometimes the nv-private folder generates and causes the build to fail due to nonexistent build file nv-private\meson.build.

This appears to have been introduced in commit 74608c34cbc0a8919b032e17b3563e7097aba4f9 on DXVK-Remix repo.

Note: This issue appears to only happen on certain systems

Steps to Reproduce

1. Clone the repository and attempt to build using dxvk-remix\build_dxvk_all_ninja.ps1
2. Build fails with error about missing tests/rtx/dxvk_rt_testing/meson.build
3. After manually deleting the dxvk_rt_testing directory, build may fail again with error about missing nv-private/meson.build

Expected Behavior

Build should complete successfully without requiring manual deletion of directories or encountering missing meson.build files.

Actual Behavior

Build fails due to missing meson.build files in the tests/rtx/dxvk_rt_testing subdirectories.
