[GoogleSans] Upstream Google Sans preloading

Copy downstream XML to preload Google Sans fonts from GMS Core to
upstream. This will be followed by CLs to cleanup downstream preloading
(crrev.com/i/3202583) and update downstream font references
(crrev.com/i/3202445).

The only change made in duplicating these files was renaming
font/accent_font.xml and font/accent_font_medium.xml to
font/google_sans.xml and font/google_sans_medium.xml, respectively.
At the time of this CL landing, there are not yet any style resources
referencing these new font resources.

The only functional change in this CL is that public Clank builds will
now also preload Google Sans, which is by design to support
https://crbug.com/1110973.
