Reviewed by Jessie Berlin.

A lot (if not the majority) of files in html/ are forms related, so it makes sense to begin splitting
them out into a separate subdirectory, html/forms.

Begin my moving FileIconLoader from platform to html/forms. It is related to HTML forms (it's only used by
the file upload element), and is not really a platform abstraction so it doesn't belong in platform.
