Replace Ambient Lights with Environment Map Lights (#17482)
# Objective

Transparently uses simple `EnvironmentMapLight`s to mimic
`AmbientLight`s. Implements the first part of #17468, but I can
implement hemispherical lights in this PR too if needed.

## Solution

- A function `EnvironmentMapLight::solid_color(&mut Assets<Image>,
Color)` is provided to make an environment light with a solid color.
- A new system is added to `SimulationLightSystems` that maps
`AmbientLight`s on views or the world to a corresponding
`EnvironmentMapLight`.

I have never worked with (or on) Bevy before, so nitpicky comments on
how I did things are appreciated :).

## Testing

Testing was done on a modified version of the `3d/lighting` example,
where I removed all lights except the ambient light. I have not included
the example, but can if required.

## Migration
`bevy_pbr::AmbientLight` has been deprecated, so all usages of it should
be replaced by a `bevy_pbr::EnvironmentMapLight` created with
`EnvironmentMapLight::solid_color` placed on the camera. There is no
alternative to ambient lights as resources.
