Normalize MIME-types we invented with /x-ft- prefix

MIME-types we invented, which neither have a widely used existing MIME-type, to use the `/x-ft-` prefix.

These MIME-type mappings changed:
- `application/x-lzip` ↦ `application/lzip`
- `application/x.ms.shortcut` ↦ `application/x-ms-shortcut`
- `application/x.apple.alias` ↦ `application/x-ft-apple.alias`
- `application/x.autodesk.fbx` ↦ `application/x-ft-fbx`
- `application/vnd.google.draco` ↦ `application/x-ft-draco`
