Don’t prepare lights (and shadow map textures) for 2D cameras (#14574)

# Objective

When running the Metal debugger I noticed that 2D cameras have shadow
map textures from `bevy_pbr` built for them. For a 2560x1440 2D camera,
this PR saves about 40mb of texture memory.

## Solution

- Added `With<Camera3d>` filter to the appropriate view queries.

## Testing

- This is a trivial fix (the examples still work)
