[Feature] Utest 测试用例推进事项 #10680
Description
Describe problem solved by the proposed feature
由于目前RTT关于组件相关的 UTEST 测试用例较为欠缺，为了更好的针对组件进行维护，需要针对重点组件进行测试用例的补充，目前准备推进的测试用例包括以下内容：
初步期望达成的目标：
- 覆盖到90%以上的API
- 部署到CI（qemu）上运行测试
文件系统
- DFSV1/V2相关API：[add][testcase]add memory pool and file system testcases. #10670
- POSIX文件系统API：[add][testcase]add memory pool and file system testcases. #10670
网络
-
LWIP 相关API：[utest][lwip]add lwip api testcase. #10675
-
NETDEV相关API：
[net/netdev]Fixed compilation errors when enabling IPv6 and IPv4 dual-stack support. #10691
[netdev]Fixed netdev_unregister missing correct return value. #10693
[lwip/core/dhcp.c]Fixed incorrect pairing of DHCP enable/disable in lwip (≤v2.0.3) #10694
[utest][netdev]add netdev api testcases. #10697 -
