Nikita Eshkeev ef90c9f857 [codeInsight] IDEA-238740 Support the jdk.internal.PreviewFeature annotation
This patch fixes the problems according to the code review, it includes:

- moving extractHighlightingFeature to HighlightingFeature and renaming it to fromPreviewFeatureAnnotation
- assuring the PreviewFeature annotation name by calling PsiAnnotation#hasQualifiedName instead of comparing the name by equals
- moving JDK_INTERNAL_PREVIEW_FEATURE to HighlightingFeature
- extracting repeating part of checking the language level to HighlightUtil#checkPreviewFeatureElement
- adding a new case "SEALED_CLASSES" to HighlightFeature#fromPreviewAnnotationName

In addition to that there is also more robust solution to detect invalid contexts in references and static imports. The test data updated accordingly.
