Create a table to store the status for translatable bundles. The table would store the following details:
- page_id - Page Id
- sortkey - Used as key to sort the bundles in the table
- bundle_type - Type of bundle: message bundle / page translation
- bundle_status - Status of the bundle, eg: tp:mark, tp:tag etc
This table will be used in Special:PageTranslation and in the future to list message bundles. The structure used should allow easy filtering of translatable bundles based on statuses and should support pagination.
