Build Error when using ENUM without 0 entry

4.24 we added a check in CompileEnum of HeaderParser.cpp to check if there is a 0 entry in the enum declaration. however consider the following the codes

UENUM(BlueprintType)

1. enum class EUSimCameraType :uint8
2. {
3. UNKNOWN = USIMAPI_CAMERA_TYPE_UNKNOWN UMETA(DisplayName = "Unknown"),
4. PINHOLE = USIMAPI_CAMERA_TYPE_PINHOLE UMETA(DisplayName = "PinHole"),
5. FISHEYE = USIMAPI_CAMERA_TYPE_FISHEYE UMETA(DisplayName = "FishEye")
6. };

while "USIMAPI_CAMERA_TYPE_UNKNOWN is defined as 0, but users still got the warning. – "'EUSimCameraType' does not have a 0 entry! (This is a problem when the enum is initalized by default)"

And more importantly by default "treat warning as errors" is on in ExternalExecution.cs of UnrealBuildTool, which will lead to build errors.
