PR583 hot fix

[aris134]

Description

PR583 resulted in some jax test failures.

The tuned HIP RMSNorm kernel can introduce small numerical jitter compared to the general kernel path. For MXFP8, these tiny differences can shift the selected scaling factor by one step, which in turn can double or halve the quantized data representation and cause bitwise comparisons to fail despite equivalent numerical behavior.

This hotfix disables precise/bitwise comparison for HIP MXFP8 test coverage while preserving the existing numerical correctness checks.
