### What this PR does / why we need it?
PR #5672 attempted to remove the -1 padding for duplicate tokens in the
decode slot_mapping when adapting PCP for MLAPO, and adopted a simpler
slicing approach. However, in the single-ops logic and mixed PD batches,
the decode slot_mapping did not eliminate the -1 and also shared the
slicing method, resulting in incorrect slot_mapping. This PR resolves
this issue, and the logic will be further consolidated in subsequent
refactoring PRs.

### What this PR does / why we need it?
This PR fixes a critical bug in the PD-separated inference pipeline
where KV cache on the Prefill (P) side was not being properly released.
The issue arises when multiple clients use the same x-request-id: to
avoid request ID collisions, both Prefill and Decode nodes append a
random suffix to the incoming x-request-id. A previous PR ensured
consistency by having the P-side pass its final request_id as
remote_request_id to the D-side via kv_transfer_param. However, during
KV cache cleanup, the D-side incorrectly used the local req_id (instead
of remote_request_id) to select the target P-side rank. This mismatch
caused the P-side KV cache to remain unreleased on certain ranks,
leading to memory leaks. This PR corrects the logic to use
remote_request_id consistently when determining the P-side rank.
### Does this PR introduce _any_ user-facing change?

### What this PR does / why we need it?
Fix the MTP test failure caused by accessing non-existent attribute
`forward_context.draft_attn_metadatas`.
**Root cause:**
In `AscendAttentionBackendImpl.update_graph_params`, the code
incorrectly accessed `forward_context.draft_attn_metadatas`, but
`ForwardContext` class doesn't have this attribute. The original code
passed this value via function parameter.
**Fix:**
Add `draft_attn_metadatas` parameter to the entire call chain:
- `update_full_graph_params` function in `acl_graph.py`
- All `update_graph_params` methods in attention backends
- Pass the parameter correctly in `eagle_proposer.py`
Also applied Gemini's suggestion to make `vllm_config=None` in
`AscendAttentionCPImpl.update_graph_params` for API consistency.

### What this PR does / why we need it?
This PR optimizes the torch_npu profiler configuration to significantly
reduce overhead and trace file size. The key changes include:
**Enable Data Simplification**: Explicitly sets data_simplification=True
in _ExperimentalConfig. This filters out unnecessary intermediate data
during profiling, drastically reducing the memory footprint and I/O
overhead.
**Use Lightweight Stack Tracing**: Replaces with_stack with with_modules
when torch_profiler_with_stack is enabled. In torch_npu, with_stack
introduces heavy latency. with_modules provides equivalent semantic
information with much lower overhead.
**Code Simplification:** Removes redundant parameter configurations in
_ExperimentalConfig by utilizing default values, making the codebase
cleaner and easier to maintain.
**Test setup:**
max length = 50, profiler + stack enabled
**Before optimization:**
Profiler data size: 651 MB
Generate time: 3 seconds
**After optimization:**
Profiler data size: 156 MB (≈76% reduction)
Generate time: <1 second
### Does this PR introduce _any_ user-facing change?
No API changes. Users profiling on Ascend will experience faster
profiling execution and smaller trace files when stack tracing is
enabled.
### How was this patch tested?
Manually verified on Ascend NPU by running vLLM with the profiler
enabled. Confirmed that trace files are generated correctly containing
necessary stack/module info, while showing the reported reduction in
size and time.

This PR removes `update_default_aclgraph_sizes`. In earlier versions, we
add this function to change default `cudagraph_capture_sizes` because
`_npu_paged_attention` degrades significantly on certain shapes (which
is included in default `cudagraph_capture_sizes` of VLLM). Now since we
use FIA as default attention op (which does not contain such performance
degradation), there is no need to add this default change. Otherwise, it
could cause some conflicts if we set a small `cudagraph_capture_sizes`
that < 20 now.

### What this PR does / why we need it?
The static kernel in torch_npu is uninstalled through Python's atexit
mechanism.
However, in vllm-ascend, when inference ends or the service stops, the
worker process is terminated. This way, ending the process does not
trigger the atexit mechanism, causing the static kernel not to be
unloaded.
When using the nougraph_ex backend and enabling the static kernel, we
registered a signal handler to explicitly unload the static kernel.
When there are many static kernels, unloading usually takes some time,
whereas vllm will directly kill the process after sending a terminate
event. Therefore, we choose to handle it by starting a new process.

### What this PR does / why we need it?
Currently, we pad the last dim of qkv to 128 before flash attention (in
`AscendMMEncoderAttention`) to get better performance on Ascend NPU.
However, the qkv padding is executed serially, which may lead to more
overhead when launching `aclnnConstantPadNd` (launch 3 times).
Since the three operations are mutually independent, we stack qkv first
and then pad them in one kernel launch. With this optimization, **TTFT**
has been reduced by **3.15%**, **peak throughput** has been increased by
**4.20%**.

**Refactor: Unify full-graph parameter update logic**
This PR consolidates the scattered full-graph parameter update logic
into a unified approach, improving code architecture and eliminating
duplication.
**Key improvements:**
1. **Unified interface**
- Create `update_full_graph_params` as the single entry point for all
full-graph updates
- Replace multiple scattered update calls with one unified function
- Remove ~50 lines of duplicated if-else logic across
`model_runner_v1.py` and `eagle_proposer.py`
2. **Better architecture**
- Move update logic to respective Backend classes
(`AscendAttentionBackend`, `AscendMLABackend`)
- Each Backend manages its own parameter update logic internally
- Simplify caller code to just dispatch to the appropriate Backend
3. **Cleaner parameter handling**
- Remove unnecessary `pcp_size` and `dcp_size` parameter passing
- Get parallel configuration directly from distributed groups
- Consistent with how other parts of the codebase obtain these values
**Why we need it:**
- **Maintainability**: Future changes only need to be made in one place
per Backend
- **Code quality**: Follows DRY principle and Single Responsibility
Principle
- **Readability**: Cleaner, more intuitive code structure
### Does this PR introduce _any_ user-facing change?
**No.** This is a pure refactoring with no functional changes - same
behavior, cleaner code.
### How was this patch tested?
- All existing unit tests pass with updated mocks
- No new tests needed (pure refactoring, no behavior changes)
- CI validates correctness
