feat(developer,windows): Support KMP Package Images as an Installer Title Image Option

### Is your feature request related to a problem? Please describe.

The keyboard installer interface as compiled with `kmc` can arrange a graphic image for decoration of the installer interface positioned horizontally at the top of the UI window. This creates a burden upon developers who must create a new image for the installer interface. It would be very convenient if the existing images used for KMP packages could be reused here.

### Describe the solution you'd like

I'd like the compiler to check if the title image dimensions are 140x250, and if so then to lay it out in the same way as is done with KMP package interfaces.

### Describe alternatives you've considered

The only alternative is to create separate images in a horizontal layout.
