Improve map view and game panel user experience

Minimizes panel mouse obstruction to scripted panel images
Prevents map view from hovering inside UI elements
Unsets province hover when not over provinces

Add `GUINode.click_mask`
	Prevents mouse interactions not within click_mask

Add `GUINode.set_click_mask_from_nodepaths`
	Generates click_mask from paths relating to GUINode textures
	Sets nodepaths to MOUSE_FILTER_IGNORE

Add CanvasLayer parent to GameSession UI nodes
Set mouse_force_pass_scroll_events to GameSession UI nodes
Set MapControlPanel mouse_filter to default (MOUSE_FILTER_STOP)

Move MapView mouse viewport changes to _input
Move MapView _action_drag released check to _input
Move MapView processing to _process
Remove viewport and window notifications
Disable if window is not focused or input is handled:
	MapView mouse interactions (including edge scrolling and drag panning)
	MapView province hover

Set mouse_filter to MOUSE_FILTER_IGNORE for ProvinceOverviewPanel province_view panel
Set ProvinceOverviewPanel click_mask path to `province_view/background`

Set mouse_filter to MOUSE_FILTER_IGNORE for Topbar topbar panel
Set Topbar click_mask path to `topbar/topbar_bg` and `topbar/topbar_paper`
