Blank assets for staging new media UI, take two.

Blank assets for staging new media UI, take two.

This CL adds new zero-length png and css assets, so that they can
be referenced in blink_platform_impl.cc (etc.) for staging, before
the main CL in WebKit lands.

The css files also have to be non-empty, else the gn mandoline builds break.  not sure why the 'cl try' on the original didn't fail.

This CL does not change any existing functionality.

It also makes the css files non-empty, since that breaks gn builds.

Hi

The previous version of this CL (https://codereview.chromium.org/1207463002/)
broke the blink roll, even though the CL try bots and CQ succeeded.  i got a
local repro and fixed it -- the empty css files don't work well with gn's way of
bundling resources for mandoline.

they are now non-empty.

thanks
