Localize on a block level

Currently localization of blocks can happen on an individual input level within the block (see attached screenshot), this leaves room for error where a user may input localization for some inputs in a block but not others (i.e. a banner heading in korean and description or image still in english).

As a user I should be able to localize an entire block. This would make sense on a top level for block options.

There should also be a warning for incomplete fields for a localized block.
