Add Qwen-3 0.6B CPU recipe

[kunal-vaishnavi]

Description

This PR adds a recipe for Qwen-3 0.6B on the CPU EP.

Motivation and Context

The Qwen-3 0.6B variant that uses KLD gradient with a ratio of 0.65 shows the best tradeoff for MMLU vs. model size when quantized. The recipes in the broader PR are for other variants.

Results

Sample size = 1000
