fix: remove cuda toolkit error message and bring back incremental model import

[louis-jan]

Describe Your Changes

This PR removes the irrelevant error message about missing CUDA toolkit dependencies since it’s now shipped by default. Bring back the legacy incremental model import naming convention.

Changes made

1. useDropModelBinaries.ts:

• The name processing for file names was modified. Any spaces in the file name are now removed before the '.gguf' extension is stripped.

2. useImportModel.ts:

• Jotai's useAtomValue was imported to access the atom state.
• downloadedModelsAtom was added to the imports, which enables tracking of already downloaded models.
• A new utility function, incrementalModelName, was introduced to handle naming conflicts. This function ensures that any model name duplicates are resolved by appending a number to the model's name.
• The naming logic for models during import was updated to use incrementalModelName for unique identification.
• Similar name processing to useDropModelBinaries.ts was applied, where spaces in model names are removed.

3. LoadModelError/index.tsx:

• A substantial block of error-handling code related to GPU settings, CUDA toolkit, and Nvidia drivers was removed. This code was responsible for rendering specific error messages when issues were detected with the GPU runtime configuration.

Overall, these changes focus on ensuring unique model name identification, simplifying error handling by removing specific GPU-related messages, and cleaning up file name processing.
