d/jak2: finish entity-table | sky-data | relocate | and the majority of default-menu (#1812)
* d/jak2: finish `entity-table`

* d/jak2: finish `sky-data`

* d/jak2: finish `relocate`

* d/jak2: halfway through `default-menu`

* d/jak2: 75% done `default-menu`....

* d/jak2: add `default-menu` to ref tests (partially)

* d/jak2: finish updating related code

* scripts: add tooling to automatically keep code from `all-types` up to date

* d/jak2: fixed vector types
