/**
* Allows a block to restrict the user interface that is displayed for editing
* that block and its inner blocks.
*
* @example
* ```js
* function MyBlock( { attributes, setAttributes } ) {
* useBlockEditingMode( 'disabled' );
* return <div { ...useBlockProps() }></div>;
* }
* ```
*
* `mode` can be one of three options:
*
* - `'disabled'`: Prevents editing the block entirely, i.e. it cannot be
* selected.
* - `'contentOnly'`: Hides all non-content UI, e.g. auxiliary controls in the
* toolbar, the block movers, block settings.
* - `'default'`: Allows editing the block as normal.
*
* The mode is inherited by all of the block's inner blocks, unless they have
* their own mode.
*
* If called outside of a block context, the mode is applied to all blocks.
*
* @param {?BlockEditingMode} mode The editing mode to apply. If undefined, the
* current editing mode is not changed.
*
* @return {BlockEditingMode} The current editing mode.
