M3-5117: Remove __data__/types.ts and update affected files

[DevDW]

Description

Removes __data__/types.ts and updates the files (mostly tests) that used it accordingly by bringing back cachedData/types.json (see https://github.com/linode/manager/pull/7777/files) to use instead.

How to test

Ensure that yarn up works with no TS errors; run the affected tests and ensure everything passes –

yarn test typesHelpers.test.ts

yarn test GetSearchEntities.test.ts

yarn test ResizeNodePoolDrawer.test.ts

yarn test BackupsTable.test.ts

yarn test BackupsDrawer.test.ts

yarn test BackupLinodes.test.ts
