Use sdkReleaseType for tagIsStable in TypeSpec projects (#45768)

* Use sdkReleaseType for tagIsStable in TypeSpec projects

For TypeSpec projects, determine tagIsStable from sdkReleaseType input
instead of using judge_tag_preview. Swagger projects continue to use
judge_tag_preview as before.

- Extract sdkReleaseType from pipeline input data
- Add is_tsp flag to distinguish TypeSpec from Swagger codegen
- TypeSpec: tagIsStable = (sdkReleaseType == 'stable')
- Swagger: tagIsStable = not judge_tag_preview(...)
- Add test_sdk_generator.py with 9 test cases covering the new logic

* Use sdkReleaseType for tagIsStable in TypeSpec projects (#45769)

* Initial plan

* Fix Black formatting in test_sdk_generator.py
