{testsdk} Migrate azure-devtools to azure-cli-testsdk

[zhoxing-ms]

Since CLI recently migrated azure-devtools code to azure-cli-testsdk and drop the dependency of azure-devtools. Related PR: #20601 Therefore, CLI extension also needs to be migrated.
Because too many modules are involved, in order to fix the issue as soon as possible to avoid blocking CI, so I modified them uniformly
