feat: add new drawer mount point

[debsmita1]

Description

Based on the spike https://docs.google.com/document/d/1nv2ITnWXeGiqjNVCFjhsEPL11M3zjha93y2KdS0ZPz0/edit?usp=sharing , this PR implements the following:
-> All two new mount points for dynamic plugins:
- application/drawer-state : Exposes the plugin's drawer state (isDrawerOpen, drawerWidth, setDrawerWidth) to RHDH via callback props
- application/drawer-content : Defines the drawer's content component along with configuration options:
id: Unique drawer identifier
priority: Numeric value determining render order (higher priority renders first)
resizable: Boolean to enable/disable drawer resizing
-> ApplicationDrawer Component, which renders all application/drawer-state components, collects drawer states via callback props, and filters for open drawers and renders the highest priority drawer content
