* Adds support for returning a custom header from `validate_block` This adds support for returning a custom header from `validate_block`. Before this, we always returned the header of the block that was validated (and still do it by default). However, after this pr it is possible to set a custom header or better custom head data that will be returned instead from `validate_block`. This can be for example when a chain wants to fork. * FMT
