[11.x] Add a new helper for context

[michaelnabil230]

This PR introduces a new helper function for managing context in applications.

Example usage:

context(['user' => auth()->user()]); // Add user information to the context

$context = context(); // Retrieve the context object

$user = context('user'); // Retrieve user information from the context

This enhancement simplifies the management of contextual data within the application, making it more efficient and readable.
