Refactor: Introduce video message record mode

This commit refactors the `ActionMode` sealed class into an enum and adds a new `RECORD_VIDEO` state. This allows for distinct actions for recording audio and video messages.

Specifically, the following changes were made:
- Converted `ActionMode` from a sealed class to an enum.
- Added `RECORD_VIDEO` to `ActionMode`.
- Updated `MessagesHistoryInputBar` to:
    - Animate the action button icon change between record modes.
    - Remove the shake animation from emoji, attachment, and mic buttons.
- Updated `MessagesHistoryViewModel` to toggle between `RECORD_AUDIO` and `RECORD_VIDEO` when the action button is clicked in a record mode.
- Added support for displaying `VIDEO_MESSAGE` attachments in `Attachments.kt`, including an animated circular preview.
- Updated `MessageBubble` to render video messages without a background, similar to stickers.
- Added `image` property to `VkVideoMessageDomain` to hold the URL for the video message preview.
- Added a new drawable `rounded_photo_camera_24` for the video record button.
- Updated `VkVideoMessageData` to parse and provide the square preview image URL to the domain model.
