Add Qwen3NextForCausalLM to mamba_like_arch#1450

Qwen3Next uses a hybrid GDN+attention architecture that requires separate KV cache groups for GDN vs standard attention layers. Add it to the mamba_like_arch list so maybe_set_mamba_kv_cache_groups_ids() sets up the cache groups correctly. Signed-off-by: Radoslaw Smyrek <radoslawx.smyrek@intel.com>
