[Feature]: Chat emojis

[lL1l1]

Describe the Feature

Ability to display text-scaled images in chat.

This helps players express themselves better with modern emoji communication in chat.
It also allows improvements for things like the resource sharing notifications by allowing generic icon-based system messages.

Expected Behavior

Steps of implementation:

1. A text superclass that can render a basic variable-size bitmap using an in-text key. The bitmap should take the left edge of the key's text and be centered vertically in the text line. The height should adjust to text font height. The width should offset the text coming after the bitmap.
2. Make sure methods like text wrapping and the textadvance lazyvar work with it.
3. Allow passing in a key->bitmap table to customize the new class.
4. Implement the new class as the text display for the chat.
5. Add ability to add additional emoji mappings for chat.
6. Create a basic emoji set for the FAF community and assign it to chat.
7. Add an emoji input box to chat based off the mappings. Put added mappings in separate categories alphabetically sorted so that mods don't mess with it too much.
8. Add onto chat's autocomplete implementation to work with the emojis.

Additional context

This would be an integration and upgrade of @4z0t's deprecated "Emojis" mod.

In the future this could be added to the lobby chat.

For some reason original pr for fa repo doesn't contain the change for emojis anymore. And source code seems to be missing on my end too.

the PR: #3300
I was unable to load the changes from the PR webpage but I went directly to chat.lua at the commit and it started loading.
