Add Roboto-Medium webfont and factor out common Roboto WebUI CSS file.

Add Roboto-Medium webfont and factor out common Roboto WebUI CSS file.

The common file prevents duplication of the same @font-face definitions,
and allows additional font weights and character sets added by one
project to be automatically available for all other Roboto users.

This CL also updates the Roboto font files from Google Fonts and removes
the .woff file, since Chrome has complete support for woff2.

BUG=439114

this is a very different set than the other CSS files had. Can you explain where
these code points came from/why they're right?

The unicode-range from the old files was actually incorrect. These ranges both
came from the output of fonts.googleapis.com. Inspecting the old range shows
that it is Cyrillic (U+460, for example, maps to Ѡ), while U+0000-00FF (which
includes all of ASCII) from the new range is a good hint that it corresponds to
Latin.

Great, thanks for explaining. Glad to have this all in one place now.
