Add emoji suggestions

[langleyd]

Add emoji suggestion character to the PatternKey and an insertEmoji action similar to slash commands(except it doesn't insert a space after the suggestion insertion)

The consumer of this will be web.

iOS and Android handle it as a no-op(just a couple of switch cases to ignore).

LGTM, thanks! It's nice to have this because I had planned adding this feature to the non-RTE editor on Android, so now we can have parity 🎉 !

Seems good for Web but few unit tests will be great!

[langleyd]

I added unit tests for the rust. The rest of the code is bindings(wasm + ffi) which we don't really test directly at the moment but will have another look.

[langleyd]

Oh i can for platforms/web/lib/suggestion.ts
