[Feature-Request] Implement Accordion Control

[FarjanaParveen]

Description

The Accordion control allows you to organize content in a collapsible format. It enables users to expand or collapse sections of content to view or hide details as needed. This feature is particularly useful for creating an organized and space-efficient user interface, where large amounts of content can be neatly displayed with minimal scrolling.

Key Features

• Data Binding: Utilizes the BindableLayout to bind data collections and populate the Accordion.
• Expand Modes: Control the expansion behavior of items based on specific requirements, such as allowing only one item to be open at a time or permitting multiple items to be open simultaneously.
• Animation: Enables animated transitions for expanding and collapsing accordion items, providing options to customize the animation duration and adjust the easing style.
