Basic UI text shadows (#17559)
# Objective

Basic `TextShadow` support. 

## Solution

New `TextShadow` component with `offset` and `color` fields. Just insert
it on a `Text` node to add a shadow.
New system `extract_text_shadows` handles rendering.

It's not "real" shadows just the text redrawn with an offset and a
different colour. Blur-radius support will need changes to the shaders
and be a lot more complicated, whereas this still looks okay and took a
couple of minutes to implement.

I added the `TextShadow` component to `bevy_ui` rather than `bevy_text`
because it only supports the UI atm.
We can add a `Text2d` version in a followup but getting the same effect
in `Text2d` is trivial even without official support.
