Refactor EmojiInput for better vue3 compatibility

This changes the way EmojiInput works internally, previously it relied on slots to get element out of nested <input> or <textarea>, however in Vue3 slots do not have elements, and this is supposedly "not public API", so changing it to use ref to root and some querySelector instead.
