### What this PR does / why we need it?
This PR is to fix a smoking test failure. Adjust mtp_proposer and
model_runner_v1 to route MTP decoding through the non‑fused MoE
implementation while keeping the overall inference flow unchanged.

### What this PR does / why we need it?
In the Deepseek technical report, it is mentioned that the embedding and
lmhead layers of the MTP layer are shared with the main model, but the
current implementation independently loads the complete embedding and
lmhead. In the Deepseek-R1 model, their weight sizes are 129280*7168 in
fp16 format, which is 1.72G.
This PR fixes the MTP layer to use the lmhead and embedding of the main
model, saving 3.45G of GPU memory in the pure DP scenario.
The current process will first create temporary spaces for the embedding
and lmhead in the mtp layer, then I will call torch.equal to determine
if the two matrices are the same. If they are the same, they will be
reused, and the previous tensor will be released.

### What this PR does / why we need it?
Original `sample_recover_tokens_kernel` of reject sampler didn't tile
the vocab size dim, whitch will cause ub overflow problem for models
with big vocab size like deepseek. This PR adds tiling to the vocab size
dim to avoid this problem.
Note that currently we just use a emperical `SUB_BLOCK_SIZE` of `4*1024`
for functionality. If in the future this kernel becomes performance
bottle neck, we can use triton autotune to optimize this. What's more,
we have to disable multibuffer of this kernel due to some accuracy
issues.

### What this PR does / why we need it?
This PR introduces the Ascend implementation of the
`dispatch_ffn_combine` kernel and wires it into the vLLM-Ascend runtime,
together with follow‑up fixes to ensure the kernel builds and runs
correctly in CI.
- Add full host and device implementation of the `dispatch_ffn_combine`
kernel under `csrc/dispatch_ffn_combine`, including tiling logic, MOE
routing helpers, and kernel utilities for quantized FFN dispatch.
- Integrate the new kernel with the PyTorch binding
(csrc/torch_binding.cpp, csrc/torch_binding_meta.cpp) and the Ascend
runtime (vllm_ascend/ascend_forward_context.py,
vllm_ascend/worker/model_runner_v1.py).
- Extend fused MoE communication and token dispatch support in
`vllm_ascend/ops/fused_moe`, adding methods/utilities needed by the new
dispatch path.
- Update quantization logic in vllm_ascend/quantization/w8a8_dynamic.py
to support the new FFN dispatch flow.
- Fix kernel build issues by adjusting `csrc/build_aclnn.sh`, CMake
configuration, and include/namespace usage in the new kernel files.
- Add an end‑to‑end nightly test
`tests/e2e/nightly/ops/test_dispatch_ffn_combine.py` and helper
utilities in `vllm_ascend/utils.py` to validate the new kernel.

### What this PR does / why we need it?
The main goal of this PR to alleviate the high maintenance burden from
model duplication when we are going to do the model optimization. Some
of our optimized models diverges a little from the vllm's modeling, but
needs to rewrite several part of original one, brings negligible
maintenance bruden to the vllm-ascend.In order to solve that, we propose
to leverage `torch.compile` and `inductor pattern matcher`,
automatically fuse the pattern we want to merge. For more details can
refer to the RFC https://github.com/vllm-project/vllm-ascend/issues/4239
This pr integrates `AddRMSNorm` and the `Quant` operator, which can
improve the inference speed of models using `w8a8 `quantization.

### What this PR does / why we need it?
Due to the requirement of the FIA operator that the **query.shape[0]**
must match **actual_seq_len[-1]**, in graph mode and multi-DP scenarios,
the query is padded to the size of **num_input_token**. This leads to
validation errors during tiling in the operator. However, since the
padding is applied at the end of the query, it does not affect the
actual execution result of the operator, and the precision remains
unaffected.
