Max image with should respect `contentWidth` & `wideWidth` of theme.json

[fabiankaegy]

Expected/Desired Behavior

When using a block / hybrid theme that contains a theme.json file the settings.layout.contentSize & settings.layout.wideSize sizes should be used to determine the maximum width attribute that is added to images.

Actual Behavior

Currently the width gets defined by the $content_width variable which is no longer needed / used in themes that have a theme.json. (See documentation: https://developer.wordpress.org/themes/basics/theme-functions/#content-width)

Lines 288 to 291 in e1e7f55

	// Constrain default image sizes to the theme's content width, if available.
	if ( $content_width > 0 && in_array( $size, array( 'thumbnail', 'medium', 'large' ) ) ) {
	$_max_w = min( $_max_w, $content_width );
	}

Because of this block themes that don't define the old $content_width variable get the fallback value of 1024px applied which leads to blurry images when the align wide / align full option is used on an image.
