add toggleAdditionalOptions action

[murat-encord]

Changes proposed in this pull request:

• Adds an optional boolean prop closeAdditionalControlsOnClickBody to disable the default behaviour of closing the additionalControls when clicking anywhere on the body.

• Introduces a new window context action toggleAdditionalControlsOpen to toggle additional controls. setAdditionalControlsOpen action required to explicitly pass a boolean and was hard to use as a toggle because the open/close boolean state is internal to the window and not exposed

the "open" at the end might imply that we want to open the tray, maybe just "toggle" is fine?

Suggested change

	/**
	* Sets the open state for the tray that holds additional controls
	*/
	toggleAdditionalControlsOpen: () => void;
	/**
	* Opens/closes the tray that holds additional controls
	*/
	toggleAdditionalControls: () => void;

Thanks for the PR! Made some tweaks - let me know how they work for you:

1. Instead of disabling closing the toolbar on window-body-click, instead makes it disable the entire overlay, so users can still interact with the body. Should be better UX.
2. Instead of adding a new method toggleAdditionalControlsOpen, added a possible 'toggle' option to the existing one that has the same effect.
