Remove camera from UiBatch (#17663)

Browse Source 
# Objective

A `TransparentUI` phase's items all target the same camera so there is
no need to store the current camera entity in `UiBatch` and ending the
current `UiBatch` on camera changes is pointless as the camera doesn't
change.

## Solution

Remove the `camera` fields from `UiBatch`, `UiShadowsBatch` and
`UiTextureSliceBatch`.
Remove the camera changed check from `prepare_uinodes`.

## Testing
The `multiple_windows` and `split_screen` examples both render UI
elements to multiple cameras and can be used to test these changes.

The UI material plugin already didn't store the camera entity per batch
and worked fine without it.
