Make inputPathToUrl work for passthrough files

[gmalecha]

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

I would like to be able to embed links to static content from generated content, e.g. a link to a PDF file from a page that contains a summary of the PDF. To do this, I set up the PDF file as a passthrough file, but I would like to reference this path via the template. It seems like inputPathToUrl does not work for passthrough files, so there isn't really any nice option to support this.

Describe the solution you'd like

I would like {{ "foo/bar.pdf" | inputPathToUrl }} to work when foo/bar.pdf is a passthrough file.

Describe alternatives you've considered
