refactor(ivy): update TNodeType (#29343)
refactor(ivy): update TNodeType (#29343)

- Remove an extra type `ViewOrElement`, which even had the same numeric value as `View`.
- Updates comment to remove part about alleged bit-masking that we could be doing here.
  We aren't using this with bitmasks, and if we were, everything would be a `NodeType.Container`,
  because it's value was `0`.
- Updates the number values to be simple, human-readable integers, since we're not using these
  with any kind of bit-manipulation.
- Add comments about each type.
