[RequiredPropertiesMissingInResourceModel] some model definitions are mistakenly identified as resource models

[FumingZhang]

Describe the bug
It seems that some definitions that are not resource models are also considered resource models.

After internal discussion, there are two points that can be taken away

1. Some models in the common type do not meet the requirements of the rule. The team will suppress checks on them and release a new version of the common type in the future to meet the requirements in RPC
2. For PRs that add preview APIs, the tool in CI will mistakenly compare with the stable API as the base, and mistakenly scan out models that are not in the stable API as newly added models
