Add debug widget into 3D view

PR Description:

Description

The new debug side panel moves all relevant debug settings into one place, from multiple into one easily accessible side
panel. Furthermore the change implemented in #58947 was missing any option to toggle this on/off.

Features in this PR:

• New checkbox for stopping scene updates
• Options moved from advanced sub-category
• Camera info moved from navigation side panel and changed the way it's shown (changing values through the new spin boxes in next PR)
• Debug depth map view default position moved from top right corner into bottom left, so it won't collide with the axis view
• The size of toolbar icons is responsive to the docked state of window

Standalone window:

Docked window:

"[feature] Create new debug widget for 3D map View\n\nThis commit adds new debug side panel (similar to navigation widget), which moves several existing options from settings/navigation panel here. Camera Info has been moved from navigation panel and from table changed into input elements (preparation for another feature). Show map tile info, Show bounding boxes, Show camera's view/rotation center, Show light sources, Show debug overlay, Debug shadow map, Debug Depth map options have been moved from advanced sub-category of options. New Stop scene updates option has been created."

Changes made to the original implementation:

• There is no added icon into toolbar, the option to open debug panel was moved to advanced sub-category of settings
• Added keyboard shortcut CTRL + SHIFT + d which opens/closes the debug panel (the 3d view has to be in standalone window to be usable, in docked mode it conflicts with another and user has to make a change to keyboard shortcuts)
