变更摘要
该 PR 修复 SIMT 协作组接口的返回类型错误，将 cooperative_groups 相关接口（num_threads()、size()、thread_rank()、meta_group_size()、meta_group_rank()）的返回类型由 unsigned long long 统一调整为 unsigned int，并同步更新测试断言及 coalesced_group、thread_block_tile 相关文档中的示例变量类型。
主要改动
-
接口声明与实现返回类型调整：在
include/simt_api/cooperative_groups.h与impl/simt_api/cooperative_groups_impl.h中，将tiled_group、coalesced_group、single_warp_thread_block_tile_base、multi_warp_thread_block_tile_base的num_threads()、size()、thread_rank()（及coalesced_group的meta_group_size()、meta_group_rank()）返回类型由unsigned long long改为unsigned int，并移除实现中的static_cast<unsigned long long>转换，直接返回底层_tiled_info字段。 -
测试断言同步更新：在
tests/api/simt_api/ascendc_case_ascend950pr_9599_simt/test_operator_simt_c_cooperative_groups.cpp中，将size()、num_threads()、thread_rank()的期望值由4ull/8ull/0ull调整为4u/8u/0u，与新的返回类型保持一致。 -
文档更新：更新
coalesced_group与thread_block_tile的接口文档（coalesced_group_intro.md、num_threads.md、size.md、thread_rank.md、thread_block_tile_intro.md），将接口原型及示例变量类型由unsigned long long调整为unsigned int。
