Add sticky monitor workspaces to the core

[dalyIsaac]

This PR includes changes to add sticky monitor workspaces to Whim's core.

Sticky Monitor Workspaces

The IMapSector now has two new dictionaries:

• StickyWorkspaceMonitorIndexMap - a dictionary that maps workspaces to the monitor indices they are sticky to.
• WorkspaceLastMonitorMap - a dictionary that maps a workspace to the last monitor it was on.

These are used to store and determine which monitors workspace can be displayed on.

Saved workspaces will regain their sticky monitor indices during startup, via the CoreSavedStateManager.

Code Clean-up and Improvements

• IWindowManager.CreateWindow has been replaced by IContext.CreateWindow.
• Replaced some references to the legacy API.
• Reduced the build time for local development by reducing code generation occurrences.
