Skip Testtest_galore_quant.py for ROCm

[petrex]

This pull request includes a change to the test/quantization/test_galore_quant.py file to improve the test environment handling. The most important change is the addition of a condition to skip the entire test if CUDA is not available or if ROCM is enabled.

Test environment handling:

• test/quantization/test_galore_quant.py: Added a condition to skip the entire test if CUDA is not available or if ROCM is enabled, ensuring compatibility and avoiding test failures in unsupported environments.

Pull Request Overview

This PR updates the test environment handling in test/quantization/test_galore_quant.py to skip the test when CUDA is not available or when running on ROCm.

• Added a conditional check to determine the appropriate test environment
• Skips the test with a custom message when conditions indicate incompatibility

Comments suppressed due to low confidence (1)

test/quantization/test_galore_quant.py:18

• [nitpick] Consider clarifying the condition by explicitly checking for ROCm support (for example, by using a dedicated helper function or a more descriptive comment) to improve readability and maintenance.

if not torch.cuda.is_available() or torch.version.hip is not None:
