[TASK] Remove stray javascript build outputs

RecordExportButton.js  has been introduced in #94622 by accident
(probably a left-over from a previous patchset re-added due to grunt watch).

The TypeScript source for Enum/Viewport/TopbarIdentifiers.js has been
removed with #78760, it is unused since then and therefore removed.
