Add MenuItem and SectionScreen blocks

[rieKITO]

What is done

• Add new main table blocks: menuItem and sectionScreens
• MenuItem was added to improve the library's UI capabilities. Since the action buttons are too large, it was decided to add a compact menuItem consisting of a label and an arrow on the right (which can be hidden if needed).
• Additionally, a SectionScreen block has been added, allowing you to create nested screens from the same primitives as the main screen, without writing UIViewControllers. Recursive nesting to any depth is possible.

What to look for

PlainTextCell has been modified. The hardcoded accessoryType = .disclosureIndicator has been removed from the configureContainer() method. The value is now set in MainAdapter.

How to check

New sections have been added to the example debug screen:

• "Menu Items" section
• "Nested Screens" section
