Fix build bdist wheel error

[yzhou103]

Motivation

Fix build bdist wheel error

Technical Details

q_dtype_w== dtype.fp8 limitation is not required，
kernelId >=0 and kernelId < len(kernels_list) can make sure that it only generates lookup map with ck kernels.
kernelId of asm kernels starts with len(kernels_list) + 1

Test Plan

PREBUILD_KERNELS=1 GPU_ARCHS="gfx942" python3 setup.py bdist_wheel

Test Result

Pull Request Overview

This PR fixes a build error when creating a binary distribution wheel by removing unnecessary code and correcting documentation strings. The main issue was an unnecessary dependency on the aiter.utility.dtypes module and a filtering condition that caused build failures.

Key changes:

• Removed unused imports and filtering logic related to q_dtype_w in the kernel generation code
• Updated outdated description strings in argument parsers to accurately reflect their purpose
