Consider add a ArmResourceDeleteSync/ArmResourceDeleteAsync in the legacy namespace

ArmResourceDeleteSync/ArmResourceDeleteAsync is deprecated. Sometimes we have some delete operations that have 200 response therefore we need to write
```
delete is ArmResourceDeleteWithoutOkAsync<
RedisCacheAccessPolicy,
Response = ArmDeletedResponse | ArmDeleteAcceptedLroResponse | ArmDeletedNoContentResponse
>;
```
by passing `OK` to `WithoutOK`. We need some template in legacy namespace to represent this.

Start by locating the legacy namespace definitions and the existing ArmResourceDeleteWithoutOkAsync template. Compare how current delete templates handle 200 responses and the OK argument. Done means the legacy namespace provides templates for delete operations with 200 responses without requiring the current WithoutOK workaround.
