Rename Etag to ETag in management plane generator

• Understand the current property naming behavior in NameVisitor.cs
• Add logic to rename Etag properties to ETag in DoPreVisitProperty methods
• Create test case to verify the Etag to ETag renaming
• Build and test the changes to ensure they work correctly
• Generate test projects to validate the changes
• Refactor to use dictionary for extensibility
• Organize code by moving dictionary closer to its usage

Summary of changes:

• Introduced _propertyNameRenamingMap dictionary to hold property name renaming mappings (currently mapping "Etag" -> "ETag")
• Renamed DoPreVisitPropertyForEtagPropertyName to DoPreVisitPropertyNameRenaming for generic extensibility
• Refactored method to use dictionary lookup instead of hardcoded string comparison
• Moved dictionary declaration to be right before the method that uses it for better code organization
• This design allows easy addition of more property name transformations in the future
• Added unit test TestTransformEtagToETag to verify the renaming behavior
• All existing tests continue to pass
• Generated test projects successfully build with the new changes
