Core Image block doesn't use align support property for Block Alignement

[fabiankaegy]

Description

The default mechanism for adding alignment supports for blocks these days is specifying it in the block supports like so:

{
    "supports": {
        "align": ["wide", "full"]
    }
}

This comes with the nice benefit of being able to override the supported align properties for any block using the blocks.registerBlockType hook.

The Core Image Block does not use this newer API jet, but instead still uses the BlockAlignmentControl manually in its BlockEdit function. Which makes it pretty much impossible to filter/extend.

Lines 331 to 334 in ee398e0

	<BlockAlignmentControl
	value={ align }
	onChange={ updateAlignment }
	/>

Proposed Solution:

remove the custom usage of the BlockAlignmentControl and replace it with the supports.align option in block.json
