CloudMigrations: Break snapshot resources out into their own table (#89575)

* create a new table for migration resources

* remove raw result bytes from db

* more snapshot resource management stuff

* integrate new table with snapshots

* pass in result limit and offset as params

* combine create and update

* set up xorm store test

* add unit tests

* save some cpu

* remove unneeded arg

* regen swagger

* fix bug with result processing

* fix update create logic so that uid isn't required for lookup

* change offset to page

* regen swagger

* revert accidental changes to file

* curl command page should be 1 indexed
