[FEATURE] Get multiple items by common key prefix from local storages

A new method `getByPrefix()` is added to the module
`@typo3/backend/storage/abstract-client-storage`, affecting its
implementations

* `@typo3/backend/storage/browser-session`
* `@typo3/backend/storage/client`

A developer is now able to obtain multiple items prefixed by a given
key either from `localStorage` or `sessionStorage`.
