[Bug]: DirectML not launching

### Checklist

- [ ] The issue has been reported before but has not been fixed yet

### What happened?

Tried to launch webui through webui-user.bat and it can't. Seems like torch_directml doesn't get installed and that the program supposes that i'm using a cuda compatible gpu.

### Steps to reproduce the problem

1. Git clone stable-diffusion-webui-forge
2. Add `--directml --skip-torch-cuda-test` to COMMANDLINE_ARGS in webui-user.bat
3. Launch webui-user.bat

### What should have happened?

It should have launched the UI.

### What browsers do you use to access the UI ?

Mozilla Firefox

### Sysinfo

I couldn't get the sysinfo dump either

### Additional information

The DirectML fork of a1111 webui works fine on my AMD Ryzen 3500U Vega 8 laptop APU (2x4GB 2400MHz).

Start with launch.py and modules/launch_utils.py, then follow initialization through modules_forge/initialization.py into ldm_patched/modules/model_management.py. Reproduce with --directml --skip-torch-cuda-test and inspect the missing torch_directml and ldm imports. Done means webui-user.bat launches the UI on the reported DirectML setup.
