[BugFix] Change count_tokens_per_expert_func declaration(Tensor -> vector<Tensor>)

[DrRyanHuang]

Motivation

修复 #5762 导致的ERNIE系列模型启动BUG，这也太坑了，只抛一个🤬🤬：

FileNotFoundError: [Errno 2] No such file or directory: '/cache_ready_signal.8978'

Modifications

函数声明处已经修改返回值为 std::vector<paddle::Tensor>

FastDeploy/custom_ops/gpu_ops/moe/deepgemm_preprocess.cu

Line 44 in 724045c

std::vector<paddle::Tensor> count_tokens_per_expert_func(

所以 C++ extension 的声明也要改：

FastDeploy/custom_ops/gpu_ops/cpp_extensions.cc

Line 517 in 724045c

paddle::Tensor count_tokens_per_expert_func(const paddle::Tensor& topk_ids,

Usage or Command
