Text presentation of emoji

[schuelermine]

Description

For emoji which have a text presentation form, add a .text symbol property on the emoji member for that emoji for the text presentation form (with Variation Selector-15 added). For instance, emoji.crossmark.text would be ❌︎.

Use Case

I sometimes find myself wanting to use an emoji, for which the emoji module is great, but sometimes I prefer a plain text style. For instance, the ❌ emoji doesn’t have a well-fitting non-emoji character, but it does have a text presentation: ❌︎

This requires support for multi-codepoint Symbols in the symbols! macro. @laurmaedje would it be okay if I pursue that? (Also, I think I'll just be taking the current list and dynamically adding all text variants) (though I don't really know how I would do that cleanly without breaking some abstractions)

We should probably build support on the shaper side first before adding support on the symbol side.

This issue should probably be transferred to typst/codex.
