CmdPal: Plain text viewer and image viewer IContent (#43964)

## Summary of the Pull Request

This PR introduces new types of IContent:  
- Plain text content – simple and straightforward, with options to
switch between UI and monospace fonts and toggle word wrap.
- It's super safe to display any random text content without having to
worry about escaping the pesky markdown.
- Image viewer content – a more polished way to display images:  
- When placed in the ContentPage, the component automatically resizes to
fit the viewport, ensuring the entire image is visible at once.
- Images can be opened in a built-in mini-viewer that lets you view,
pan, and zoom without leaving the Command Palette. (Doing this directly
on the page proved to be a UX and development headache.) Fully
keyboard-controllable, so there’s no need to take your hands off the
keys.

## Pictures? Pictures!
