Auto-capitalize labels also for fields whose name or camelCase/CamelCase

When dropping a field in a layout, Studio replaces underscores with spaces, so for example, dropping the myschema:expiration_date field creates the Expiration date label (and hopefully, soon, the fully Word-Capitalized Expiration Date label, see NXS-2871)

But if the field is camelCase or CamelCase, no space is used: dublincore:LastContributor => LastContributor. So, the ticket is about "Please, also create nice labels for camelCase field names":
dublincore:LastContributor => Last Contributor
myschema:veryLastContributor => Very Last Contributor
