Apply page bleeds to PDF output

The page bleeds were not being applied to the PDF output and the legacy single page bleed option was being applied even if it couldn't be applied correctly.

We want multi-page documents to use their bleed settings.

REFACTORING: After a poll to find out if outdated bleed and size options came to 89% for Remove the options but add information as to where they've been moved to I've decided to refactor the extensions that require a page size boolean, a bleed double or an exportId string. All of these options are available on the cli, the export dialog and the pages tool. Some further UX work might be needed to make sure this cleanup doesn't cause further issues.
