Standalone editor: Remove dependencies to enums Part 1

[JiuqingSong]

Remove dependencies to existing enums from old code. Some enums can be converted into string literal type, some are used for persist content so we need to keep them for compatibility and convert to regular enum (non-const) instead so that we don't need to general "Compatible*" types any more.

• EntityOperation: Create a string literal type in roosterjs-content-model-editor package instead
• BulletListType: Create a new enum (non-const) type in roosterjs-content-model-types package
• NumberingListType: Create a new enum (non-const) type in roosterjs-content-model-types package
• TableCellMetadataFormat: Create a copy in roosterjs-content-model-editor package
• TableBorderFormat: Create a new enum (non-const) type in roosterjs-content-model-types package
• FormatState: Move the content into ContentModelFormatState type
