Respect enum values for TurboModule c++ codegen

Summary:
Defining an enum like this:

```js
export enum CustomPropertyEditor {
  BitMask = 0,
  Entity = 1,
  Slider = 2,
  AudioEvent = 3,
  CollisionLayer = 4,
  MaterialComponentDeprecatedProperty = 5,
  MeshMaterialList = 6,
  Submesh = 7,
  // CoreUiLayout (8) removed — rendered identically to ClassOrList
  MaterialMapJson = 9,
  AnimationTable = 10,
  SkeletonAsset = 11,
  NavMeshAreaType = 12,
  VFXAsset = 13,
  Table = 14,
  VariableTable = 15,
  AudioBus = 16,
  LodSettings = 17,
  WorldSearch = 18,
  EntityMaterialList = 19,
  NpcId = 20,
  LightingModelVersion = 21,
  PlatformSelector = 22,
  ComponentReference = 23,
}
```
(notice number 8 ), will cause the generated enum to actually look like:
```
  enum class NativeEditableObjectModuleCustomPropertyEditor {
    BitMask, Entity, Slider, AudioEvent, CollisionLayer,
    MaterialComponentDeprecatedProperty, MeshMaterialList, Submesh,
    MaterialMapJson, AnimationTable, ...
  };
```

in other words, the values don't match up after the core ui value. This is quite dangerous and I'm surprised no one has ever noticed that 

This diff fixes things such that if an integer value is explicitly assigned, the value is preserved in the generated enum.
