linux-yocto-dev: introduce dt-validation PACKAGECONFIG

Add a PACKAGECONFIG to control which type of dt-validation
is installed (full, or wrapped).

This is currently in linux-yocto-dev, as 5.16 introduces
the functionality of required dt schema validation.

Other v5.16 providing recipes can use the base functionality
as they desire (with or without PACKAGECONFIG).

Over time, we can migrate the support the the core
kernel classes .. in particular when more providers are at
v5.16+
