Rename TargetCamera to UiTargetCamera (#17403)
# Objective

It's not immediately obvious that `TargetCamera` only works with UI node
entities. It's natural to assume from looking at something like the
`multiple_windows` example that it will work with everything.

## Solution

Rename `TargetCamera` to `UiTargetCamera`.

## Migration Guide

`TargetCamera` has been renamed to `UiTargetCamera`.
