[0.18.0][cherry-pick][BugFix]Fix compilation errors for operators dispatch_gmm_combine_decode/moe_combine_normal/moe_dispatch_normal (#7844)

**What this PR does / why we need it?**
pick from https://github.com/vllm-project/vllm-ascend/pull/7114

Fix compilation errors encountered when building versions later than
b020 for the following operators:
dispatch_gmm_combine_decode, moe_combine_normal, moe_dispatch_normal
**Root Cause**
After the b020 version update, the original moe_distribute_base.h file
was updated and its definitions changed, which caused compilation
failures for the above three operators that depend on this file.
**Solution**
We have added a dedicated copy of moe_distribute_base.h into the
implementation of these three operators, ensuring stable compilation
independent of framework version updates.

**Does this PR introduce any user-facing change?**
No. There are no user-facing changes; this fix only resolves compilation
issues without affecting functionality or user behavior.

**How was this patch tested?**
vLLM version: releases/v0.18.0
