c7e30ae4dd MX: Remove redundant PLATFORM_SUPPORTS_MX_GEMM constant (#164320) 
Deleted duplicate definition of PLATFORM_SUPPORTS_MX_GEMM, was introduced in https://github.com/pytorch/pytorch/pull/162209
Also, adjusted BLOCK_SIZE and fp4_scaling_dtype in test_matmul_cuda.py to enable test_blockwise_nvfp4_compile on ROCm.

7304b9e7d2 [ROCm] fix carveout feature (#164303) 
Fixes #164271.

Carveout had been applied with an opposite bitmask. Besides being incorrect, this lead to flaky unit test behavior due to carveout being too high.

8df3f2fa98 Revert new-test part of #163829 (#164259) 
Summary:

New test sizes for `test_scaled_mm_vs_emulated_block_wise` all fail with

```
RuntimeError: Invalid scaling configuration
```

Disable these new tests for now (the remaining test is a parametrized
version of the original test case)

Test Plan:

`pytest test/test_scaled_matmul_cuda.py`
