ub->gm传递l2_cache_ctl参数

[and0d0]

TODO：
增加兼容性，保持默认l2_cache_ctl=0，显式传值时则使用显式值,ci中

• 高层 pto.mte_ub_gm 增加了 l2_cache_ctl参数
• 底层 pto.copy_ubuf_to_gm 里原来的 reserved 语义改成 l2_cache_ctl
• 更新相关 VPTO emitter/接口处的字段命名和语义，使它表示 reserved -> L2 cache policy

你现在在审查 GitHub PR。

仓库：hw-native-sys/PTOAS
PR：#920 ub->gm传递l2_cache_ctl参数
作者：and0d0
base branch：origin/main
head branch：HEAD（当前已 checkout 到 PR head）

要求：
1. 只审查这个 PR 相对 origin/main 的改动，必要时可以看上下文文件。
2. 重点找真实的 correctness / regression / contract mismatch / CI / runtime / compatibility 问题。
3. 不要提纯风格建议，不要提低价值猜测。
4. 严格按优先级输出：
   - P1：高概率会导致错误结果、编译/运行失败、严重回归、发布阻断
   - P2：重要缺陷、行为回归、遗漏校验/测试、较大兼容性问题
   - P3：次要但明确可改的问题
5. 如果没有问题，summary 直接写：未检查到 PR #920 存在问题，并返回 findings=[]。
6. 如果有问题，summary 简洁概括，findings 里每条都要给出：
   - severity
   - title
   - body（说明为什么是问题，尽量具体）
   - file（尽量给相对路径）
   - line（能确定就填整数，否则 null）

建议先查看：
- git status --short
- git diff --stat origin/main...HEAD
- git diff --unified=80 origin/main...HEAD

最终输出必须严格匹配 JSON schema。

Code Review

This pull request introduces support for GM store-side L2 cache control in the pto.mte_ub_gm and pto.copy_ubuf_to_gm operations by replacing a previously reserved field with the l2_cache_ctl parameter. The changes include updates to the dialect definition, parser, printer, verifier (ensuring constant values fit in the [0, 15] range), LLVM emitters, and documentation. Existing tests and examples have been updated to include the new parameter, and a new test file has been added to verify its roundtrip and expansion. There are no review comments, so I have no feedback to provide.
