add a default font (#8445)
# Objective

- Have a default font

## Solution

- Add a font based on FiraMono containing only ASCII characters and use
it as the default font
- It is behind a feature `default_font` enabled by default
- I also updated examples to use it, but not UI examples to still show
how to use a custom font

---

## Changelog

* If you display text without using the default handle provided by
`TextStyle`, the text will be displayed

//! Simple text rendering benchmark.
//!
//! Creates a `Text` with a single `TextSection` containing `100_000` glyphs,
//! and renders it with the UI in a white color and with Text2d in a red color.
