[DO NOT MERGE] chore: system aware icons storybook in menu fast follows

[Rajdeepc]

Description

This PR introduces a SystemAwareMenu class that demonstrates that the component only overrides the update lifecycle method to re-render itself and cascade the system context to its children. This minimalist approach allows the system context to flow through the component tree and ensures all descendant components can respond to system changes.

This serves as a container component that can wrap any menu or other component, providing system resolution capabilities through Lit's slot mechanism. This approach allows components to automatically adapt to system context changes (e.g., Spectrum 1, Spectrum 2, Express) without requiring direct modification of each individual component.

Features

• Added a system-aware menu component that detects the current system context
• Created a demonstration story showing its usage with standard menu components
• Allows icons and other system-dependent UI elements to automatically adapt

TODO

• This is a temporary solution for fast follows. Future implementation should handle this either via:
  1. Context-aware icons that can directly consume system context without wrapper components
  2. A more robust contextProvider implementation using @lit/context throughout the codebase

How has this been tested?

• Test case 1

  1. Go here
  2. Switch between system
  3. Check the icons with the menu items are changing based on system

• Test case 2

  1. Go here
  2. Do this

• Did it pass in Desktop?

• Did it pass in Mobile?

• Did it pass in iPad?

Note: This change has been made for the design to sign off on our Menu fast follows, but to make it more robust we would need to update our context Switcher(System Resolver) to also cascade the context of system down to slotted content also. Lit's context API doesn't allow this out of the box but we can update SystemResolverController to extend this capability. Let this PR be open for now, I will make the necessary changes on a high level which would need some deeper dive.
