core: drop legacy receipt types (#26225)

This PR drops the legacy receipt types, the freezer-migrate command and the startup check. The previous attempt #22852 at this failed because there were users who still had legacy receipts in their db, so it had to be reverted #23247. Since then we added a command to migrate legacy dbs #24028. As of the last hardforks all users either must have done the migration, or used the --ignore-legacy-receipts flag which will stop working now.
