feat: message composer (#2669)

### 🎯 Goal

Provide a message composition API supported by reactive state layer from
stream-chat. The message composition logic has been moved to
stream-chat. The logic kept in stream-chat-react is related only to the
browser event handling.

Depends on:
- GetStream/stream-chat-js#1495
- GetStream/stream-chat-css#328

### 🛠 Implementation details

The message composition now relies on `MessageComposer `instance. The
instance is available for the channel message list, thread message list
and for editing a specific message. The `MessageComposer` instance
should be accessed via `useMessageComposer` hook, that identifies the
correct context (channel, thread, message).

### 🎨 UI Changes

No changes

BREAKING CHANGE: `Channel` props `dragAndDropWindow` &
`optionalMessageInputProps` have been removed, use
`WithDragAndDropUpload` component instead (#2688)
BREAKING CHANGE: Attachment identity functions moved to stream-chat-js
(e.g. isFileAttachment...)
BREAKING CHANGE: Remove ChatAutoComplete, AutoCompleteTextarea,
DefaultSuggestionList, DefaultSuggestionListItem and introduce
TextareaComposer, SuggestionList, SuggestionListItem
BREAKING CHANGE: Remove defaultScrollToItem function previously used by
SuggestionList
BREAKING CHANGE: Removed DefaultTriggerProvider component
BREAKING CHANGE: Remove from Channel props - acceptedFiles,
enrichURLForPreview, enrichURLForPreviewConfig, maxNumberOfFiles,
multipleUploads, TriggerProvider
BREAKING CHANGE: Removal of acceptedFiles, debounceURLEnrichmentMs,
enrichURLForPreview, findURLFn, multipleUploads, onLinkPreviewDismissed,
quotedMessage from ChannelStateContext
BREAKING CHANGE: Changed signature for functions sendMessage and
editMessage in ChannelActionContext
BREAKING CHANGE: Changed signature for handleSubmit
BREAKING CHANGE: Removed setQuotedMessage from ChannelActionContext
BREAKING CHANGE: Removed types MessageToSend, StreamMessage,
UpdatedMessage in favor of LocalMessage or RenderedMessage
BREAKING CHANGE: Removed Trigger generics from ChannelProps
BREAKING CHANGE: Message input state as well as the API is now kept
within MessageComposer instead of MessageInputContext
BREAKING CHANGE: Renamed useMessageInputState to useMessageInputControls
as it does not handle the composition state anymore
BREAKING CHANGE: Removed from MessageInputProps - disabled,
disableMentions, doFileUploadRequest, doImageUploadRequest,
errorHandler, getDefaultValue, mentionAllAppUsers, mentionQueryParams,
message, noFiles, urlEnrichmentConfig, useMentionsTransliteration,
additionalTextareaProps do not expect default value anymore
BREAKING CHANGE: Changed the signature of MessageInput prop
overrideSubmitHandler
BREAKING CHANGE: Local attachment and link preview types moved to
stream-chat
BREAKING CHANGE: The SuggestionListItem UI components for
TextareaComposer receive tokenizedDisplayName instead of itemNameParts
BREAKING CHANGE: Removed duplicate types SendMessageOptions,
UpdateMessageOptions which should be imported from stream-chat instead
BREAKING CHANGE: Removed type LinkPreviewListProps - LinkPreviewList
does not have any props anymore
