fix(GizmoHelper): allow GizmoHelper to be used with camera-controls

[a3ng7n]

When using camera-controls sets target via the getTarget method, and updates the control position via the setPosition method.

Why

Allows GizmoHelper to be used alongside CameraControls/camera-controls.
resolves #1399

What

Fixes two issues:

1. CameraControls doesn't expose a target property directly - so when focusPoint is set at animation start, get the target via CameraControls getTarget instead.
2. CameraControls doesn't seem to like having its camera moved directly, and will continuously attempt to reset the mainCamera's position - the fix is to call CameraControls setPosition method after the mainCamera's position is updated, and before it has a chance to revert it.

Checklist

• Ready to be merged

I did create a storybook entry that's just a duplicate of the GizmoHelper story below but using CameraControls to test the fix out - but I didn't think it was really value added / worthy of another tutorial entry

drei/.storybook/stories/GizmoHelper.stories.tsx

Lines 51 to 86 in f4f910f

	const GizmoHelperScene1 = (props: ComponentProps<typeof GizmoHelper>) => {
	return (
	<React.Suspense fallback={null}>
	<Tokyo />
	<GizmoHelper {...props}>
	<GizmoViewcube />
	</GizmoHelper>
	<OrbitControls makeDefault />
	</React.Suspense>
	)
	}
	export const GizmoHelperSt1: Story = {
	name: 'Cube',
	render: (args) => <GizmoHelperScene1 {...args} />,
	} satisfies Story
	const GizmoHelperScene2 = (props: ComponentProps<typeof GizmoHelper>) => {
	return (
	<React.Suspense fallback={null}>
	<Tokyo />
	<GizmoHelper {...props}>
	<GizmoViewport />
	</GizmoHelper>
	<OrbitControls makeDefault />
	</React.Suspense>
	)
	}
	export const GizmoHelperSt2: Story = {
	name: 'Viewport',
	render: (args) => <GizmoHelperScene2 {...args} />,
	} satisfies Story
