feat: Add emojis endpoint

[PatryQHyper]

Is your feature request related to a problem? Please describe.
I want to build a chatbot and I would like to have an interactive text field input in my app where I can prompt emojis (as images shown). Also I would love to use it in my donate platform during alerts sent to OBS (streamer can use Kicks emojis in OBS widget).

Describe the solution you'd like
For example GET /v1/emotes with optional broadcaster_user_id. If broadcaster_user_id is set then only array of broadcasters emoji is sent back. If broadcaster_user_id is not sent/is a null then return an array of global Kick emojis.

Describe alternatives you've considered
Maybe add emojis to /v1/channels, but I don't know where to put global emojis then.

Additional context
Something like https://dev.twitch.tv/docs/api/reference/#get-channel-emotes and https://dev.twitch.tv/docs/api/reference/#get-global-emotes

this would also be great for chat overlays and emote statistics

For chat clients, having an endpoint that gets the currently authenticated user's emotes would be useful. The other platform has this under https://dev.twitch.tv/docs/api/reference/#get-user-emotes. Otherwise, it would be impossible to show a user their available emotes.
