Schema won't load when special characters are used in Flex Field Layout names

[jasonbahl]

Description

When a Flex Field Layout contains non-ascii characters in the layout name, the Schema fails to load.

Steps to reproduce

1. Add an ACF Field of the "flexible_content" field type to an ACF Field Group
2. Add a layout to the field with the label: Výchozí konfigurovatelné Hero
3. try and load the GraphQL Schema
4. see errors

I would expect for the Schema to still generate, but leaving out any types/fields that are invalid, and providing a debug message explaining the problem.

PHP or JSON export of the ACF Field Group(s)

Additional context

I believe we need some validation here: https://github.com/wp-graphql/wp-graphql/blob/develop/src/Type/WPObjectType.php#L109

To ensure that field names are valid before attempting to apply them.
