Decouple BackgroundColor from UiImage (#11165)
# Objective

Fixes https://github.com/bevyengine/bevy/issues/11157.

## Solution

Stop using `BackgroundColor` as a color tint for `UiImage`. Add a
`UiImage::color` field for color tint instead. Allow a UI node to
simultaneously include a solid-color background and an image, with the
image rendered on top of the background (this is already how it works
for e.g. text).

## Changelog

- The `BackgroundColor` component now renders a solid-color background
behind `UiImage` instead of tinting its color.
- Removed `BackgroundColor` from `ImageBundle`, `AtlasImageBundle`, and
`ButtonBundle`.
- Added `UiImage::color`.
- Expanded `RenderUiSystem` variants.
- Renamed `bevy_ui::extract_text_uinodes` to `extract_uinodes_text` for
consistency.

## Migration Guide

- `BackgroundColor` no longer tints the color of UI images. Use
`UiImage::color` for that instead.
- For solid color buttons, replace `ButtonBundle { background_color:
my_color.into(), ... }` with `ButtonBundle { image:
UiImage::default().with_color(my_color), ... }`, and update button
interaction systems to use `UiImage::color` instead of `BackgroundColor`
as well.
- `bevy_ui::RenderUiSystem::ExtractNode` has been split into
`ExtractBackgrounds`, `ExtractImages`, `ExtractBorders`, and
`ExtractText`.
- `bevy_ui::extract_uinodes` has been split into
`bevy_ui::extract_uinode_background_colors` and
`bevy_ui::extract_uinode_images`.
- `bevy_ui::extract_text_uinodes` has been renamed to
`extract_uinode_text`.
