[Main2Main] Upgrade vLLM to 0303 (#6944)

### What this PR does / why we need it?
break:
- https://github.com/vllm-project/vllm/pull/34102 
Disable_full param replaced with valid_modes/invalid_modes API
- https://github.com/vllm-project/vllm/pull/35503
Now must return float compilation_time
- https://github.com/vllm-project/vllm/pull/35564
New sequence_lengths param added
- https://github.com/vllm-project/vllm/pull/33807
A check was performed (if runner_backend != "auto")
- https://github.com/vllm-project/vllm/pull/34861
`BaseDeviceCommunicator` now accesses PyTorch's internal `pg_map` to
check process group state
- https://github.com/vllm-project/vllm/pull/35274

**Important change:**
- https://github.com/vllm-project/vllm/pull/28672

`matcher_utils` directly accesses `torch.ops._C.*` during the import
phase. In the Ascend environment, some unregistered ops trigger
`AttributeError`, causing e2e initialization failure.

https://github.com/vllm-project/vllm/blob/main/vllm/compilation/passes/fusion/matcher_utils.py#L29

This PR adds temporary compatibility placeholders (rms_norm,
fused_add_rms_norm, rotate_embedding, static/dynamic fp8 quant,
silu_and_mul) to
`vllm_ascend/patch/platform/patch_fusion_matcher_compat_ops.py` to
ensure no crashes during the import phase. Upstream repairs will be
considered later.

### Does this PR introduce _any_ user-facing change?

### How was this patch tested?

- vLLM version: v0.16.0
- vLLM main:

 #    Future Plan:

+# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+#   1. `torch.ops._C.rms_norm`, `torch.ops._C.fused_add_rms_norm`,
+#    Why:
+#       upstream vLLM initializes fusion matcher global operators at import time.
+#       On Ascend environment these symbols may be absent and cause import failure.
+#    How：
+#       inject placeholders only when the symbols are missing so import can continue.
+#    Related PR (if no, explain why):
+#       temporary compatibility patch before upstream adjustment is merged.
+#    Future Plan:
+#       remove this patch once upstream no longer requires these global symbols or
+#       provides a backend-safe initialization path.
