[Bug] AMD Radeon RX 9070 XT (RDNA 4) not detected in WSL 2 (OpenCL/D3D12)

### Windows Version

Microsoft Windows [Version 10.0.26200.7623]

### WSL Version

2.6.3.0

### Are you using WSL 1 or WSL 2?

- [x] WSL 2
- [ ] WSL 1

### Kernel Version

6.6.87.2-1

### Distro Version

Ubuntu 24.04 LTS

### Other Software

Software: GROMACS 2024
Drivers: mesa-opencl-icd, ocl-icd-libopencl1, clinfo
Host GPU Driver: AMD Adrenalin Edition (Latest 2026 version for RX 9070 XT)

### Repro Steps

1. Setup a PC with AMD Ryzen 5 9600X (Zen 5) and AMD Radeon RX 9070 XT (RDNA 4).
2. Install Windows 11 and WSL 2 (Ubuntu 24.04).
3. Install standard OpenCL packages: `sudo apt install mesa-opencl-icd clinfo`.
4. Export library paths: `export LD_LIBRARY_PATH=/usr/lib/wsl/lib:$LD_LIBRARY_PATH`.
5. Verify `/usr/lib/wsl/lib` contains `libd3d12.so`.
6. Run `clinfo`.

Note: I also tried using the official AMDGPU-install script with `--no-dkms` --usecase=opencl, but it failed with "undefined symbol: amdgpu_va_get_start_addr".

### Expected Behavior

The output of `clinfo` should list the AMD Radeon RX 9070 XT device under the "Microsoft Direct3D12" platform or "AMD Accelerated Parallel Processing" platform, allowing OpenCL applications (like GROMACS) to utilize the GPU.

### Actual Behavior

`clinfo` shows 0 devices found.

Output from clinfo:
Number of platforms: 1
Platform Name: Clover (or AMD Accelerated Parallel Processing)
Number of devices: 0

When checking logs/errors with AMD proprietary drivers, it suggests missing kernel symbols for RDNA 4 addressing in the WSL kernel: "dlerror: /lib/x86_64-linux-gnu/libRusticlOpenCL.so.1: undefined symbol: amdgpu_va_get_start_addr"

### Diagnostic Logs

Start by reproducing the report in WSL 2 on Ubuntu 24.04 with clinfo and the listed OpenCL packages, then inspect /usr/lib/wsl/lib and the reported libRusticlOpenCL.so.1 symbol error. No source file or test is named; done means the RX 9070 XT appears as an available OpenCL device and GROMACS can use it.
