[BugFix] fix paddle optional get assert in sm103

[zoooo0820]

Motivation

• 修复sm103下开启FA4出现的paddle optional 相关的assert报错

/usr/local/lib/python3.12/site-packages/paddle/include/paddle/utils/optional.h:563: paddle::optional<T>::reference_const_type paddle::optional<T>::get() const [with T = paddle::Tensor; reference_const_type = const paddle::Tensor&]: Assertion `this->is_initialized()' failed.

问题原因：

1. gqa_rope_write_cache 会被FA4调用，其实现中对cache_k_dequant_scales 等paddle::optional<paddle::Tensor> 类型，直接使用了cache_k_dequant_scales.get()而没有检查是否为null；此问题在此前测试中已经暴露，并针对这个kernel在2.5分支中做了修复 https://github.com/PaddlePaddle/FastDeploy/pull/7311/changes ，但没有同步到dev/2.6分支
2. sm103才出现上述问题的原因：针对sm90/100的编译中有"-DNDEBUG"选项，但未对sm103添加，该选项会移除标准 assert，所以在其他设备上未遇到此问题。
3. 在同时存在多个编译架构时，如[90,100,103]，由于90/100已经添加上述编译选项，在sm103上运行也不存在问题；但单独执行 build.sh 或 单独指定架构 [103]会触发上述Bug

修复考虑：

类似问题1，可能还有较多其他kernel存在对paddle::optional<paddle::Tensor> 类型的不规范调用，潜在修改影响面较大，需要进一步筛查并修改；先为sm103完善编译选项适配，同样能解决问题

• [BugFix] fix paddle optional get assert in sm103（现有标题格式合规，无需修改）

PR 描述建议（可直接复制）：

## Motivation
Fix paddle optional get assert in sm103, as following:
`paddle::optional<T>::get() const [with T = paddle::Tensor]: Assertion 'this->is_initialized()' failed` (in `paddle/utils/optional.h:563`)

## Modifications
在 `custom_ops/setup_ops.py` 中为 SM103 架构添加以下修改：
1. 新增 `get_gencode_flags()` 中 `cc_val == 103` 分支，使用 `arch=compute_103a,code=sm_103a` gencode flags
2. 新增 `has_sm103 = 103 in sm_versions and nvcc_version >= 13.0` 检测变量（需 NVCC ≥ 13.0）
3. 更新 `has_generic_fp8` 排除 SM103，避免走通用 FP8 路径
4. 将 SM103 加入 `-O3 -DNDEBUG` 编译参数块（修复 paddle optional assert 根因）
5. 将 SM103 归入 SM100 Blackwell 配置块

总体评价

SM103 的编译支持添加逻辑清晰，与现有 SM90/SM100 处理模式保持一致，-DNDEBUG 修复路径符合项目惯例。仅 PR 描述两个空段落需补 N/A，无阻塞性技术问题。
