[Feat]Xlite Qwen3-vl Support (#5228)

### What this PR does / why we need it?
This patch adds support for the Qwen3-VL model in Xlite. For more
details about Xlite, please refer to the following
link:https://atomgit.com/openeuler/GVirt/blob/master/xlite/README.md.
The latest performance comparison data between xlite and the default
aclgraph mode is as follows:

### Does this PR introduce _any_ user-facing change?
XLite graph mode supports the Qwen3-VL model.

### How was this patch tested?
vLLM version: v0.12.0

 There are two kinds for graph mode supported by vLLM Ascend:
 - **ACLGraph**: This is the default graph mode supported by vLLM Ascend. In v0.9.1rc1, Qwen and Deepseek series models are well tested.
-- **XliteGraph**: This is the euler xlite graph mode. In v0.11.0, only Llama and Qwen dense serise models are supported.
+- **XliteGraph**: This is the openeuler xlite graph mode. In v0.11.0, only Llama, Qwen dense series models, and Qwen3-vl are supported.
 
 ## Using ACLGraph
 ACLGraph is enabled by default. Take Qwen series models as an example, just set to use V1 Engine is enough.
