[BugFix][Core] Fix a bug running multi-modal with ascend_scheduler

[whx-sjtu]

This PR fix the bug related with running multi-modal models with AscendScheduler. This bug was introduced by PR #2372 by using the same parameter names as vLLM with different default values. The error is as following:

Currently I fix this bug by changing the default values of these two parameters to align with vLLM. Please take a look: @Csrayz @frankie-ys @xueliangyang-oeuler @wangxiyuan

• vLLM version: v0.11.0rc3
• vLLM main: vllm-project/vllm@17c540a

Code Review

This PR fixes a bug when running multi-modal models with AscendScheduler. The fix involves renaming configuration parameters in AscendSchedulerConfig to avoid conflicts with the base SchedulerConfig from vLLM. This is a good approach. The implementation looks correct, but I found that one of the new parameter names is misleading, which could lead to confusion and incorrect usage. I've provided a suggestion to improve the naming for better clarity and maintainability.

@Csrayz can you take a look at this change?

@Csrayz can you take a look at this change?

Today I found that the meaning of these two parameters is aligned with vLLM. The problem lies in default values. We should just align the default valuse with vLLM. cc @Csrayz @wangxiyuan
