App mode - Unify menus - 2 (#9023)

## Summary

Updates subgraph breadcrumbs menu, workflow tabs context menu & linear
mode menu to use a single implementation.
Adds new menu items for enter/exit app mode  
Hides menu when in builder mode

## Changes

- **What**: Changes the components to use either a reka-ui context menu
or dropdown, with a standard inner list
- **Breaking**: Remove existing linear toggle from sidebar as it is now
in the menu


## Screenshots (if applicable)
It looks basically identical other than the icon changes based on mode:
