[TASK] Extract default inline frontend JavaScript

This change extracts dynamically added frontend JavaScript `openPic`
and `linkTo_UnCryptMailto` which are extracted to static file
`EXT:frontend/Resources/Public/JavaScript/default_frontend.js`.
Mentioned file is loaded automatically as async script element.

As a result, view-helper `<f:uri.email>` became obsolete, which
is deprecated and considered to be removed with TYPO3 v12.0.
