Arguments defined on Interface Fields are not inherited by the fields on the Implementing Object Type

[Jason Bahl]

Description

When registering an Interface Type with fields that have arguments, then registering an Object Type that implements that Interface, the fields of the Interface Type are inherited by the ObjectType, but the argument(s) on the fields are not inherited, causing invalid schema issues.

Steps to reproduce

1. register an interface type that contains a field with an argument:

register_graphql_interface_type( 'InterfaceWithArgs', [
	'fields' => [
		'fieldWithArgs' => [
			'type' => 'String',
			'args' => [
				'interfaceArg' => [
					'type' => 'String',
				],
			],
			'resolve' => function( $source, $args ) {
				return $args['arg'];
			}
		],
	]
] );

2. register an object type that contains a field with the same name, but with no arguments:

register_graphql_object_type( 'ObjectTypeImplementingInterfaceWithArgs', [
	'interfaces' => [ 'InterfaceWithArgs' ],
	'fields' => [
		'fieldWithArgs' => [
			'type' => 'String',
			'resolve' => function() {
				return 'object value';
			}
		],
	],
] );

3. Register a field to add the Types to the Schema:

register_graphql_field( 'RootQuery', 'interfaceArgsTest', [
	'type' => 'ObjectTypeImplementingInterfaceWithArgs',
	'resolve' => function() {
		return true;
	},
]);

4. Open the GraphQL IDE and see the following error:

Interface field argument InterfaceWithArgs.fieldWithArgs(interfaceArg:) expected but 
ObjectTypeImplementingInterfaceWithArgs.fieldWithArgs does not provide it.
