feat: add new message action list and reaction selector UI

[khushal87]

🎯 Goal

This PR introduces a new message menu, removing the previous MessageOverlay.

The new components, as per the diagram, are introduced:

🛠 Implementation details

• Remove props MessageActionList, MessageActionListItem, MessageOverlay, messageTextNumberOfLines, OverlayReactions, OverlayReactionsAvatar, OverlayReactionsItem from the OverlayProvider and add them to Channel component through MessagesContext.
  The message Menu is brought down the hierarchy, so we removed the message overlay context completely.
• Remove usage of setData, setOverlay, onLongPress, onPress, and onPressIn prop from Message.tsx. The last three are removed in favour of similar props on MessagesContext and are, therefore, not needed. The setData, setOverlay props are removed as we removed the message overlay context and the overlay prop in overlay context accepts 'alert' | 'gallery' | 'none' now on. The MessageOverlay prop is introduced.
• The useMessageActions hook doesn’t take setOverlay anymore but takes in dismissOverlay.
• The MessageContext has a new prop - dismissOverlay. The definition of showMessageOverlay is changed to (showMessageReactions?: boolean) => void;.
• The isMessageActionsVisible is changed to showMessageReactions in messageAction.ts.
• Add a UI component, BottomSheetModal
• Remove the error, isMyMessage, isThreadMessage, message, and messageReactions props from OverlayContext.

Also fixes #1734
