Revert recent changes to the Fullscreen UA style sheet

Revert recent changes to the Fullscreen UA style sheet

This reverts four recent CLs:

 * Match the Fullscreen spec's CSS as far as currently practical:
   https://codereview.chromium.org/974783002

 * Move translate:none to the standard Fullscreen UA style sheet:
   https://codereview.chromium.org/1014853003

 * Remove border and padding from iframes in fullscreen:
   https://codereview.chromium.org/1032113002

 * Move iframe border/padding to the standard Fullscreen UA style sheet:
   https://codereview.chromium.org/1032253002

There are multiple unresolved regressions due to the changes:

 * Weird distorted page seen after exiting from full screen mode in
   Sleepy Jack app:
   https://code.google.com/p/chromium/issues/detail?id=468278

 * 'Print Preview' fails on 'Awesome-3d-clock' app:
   https://code.google.com/p/chromium/issues/detail?id=470057

 * Unable to toggle out of fullscreen mode after clicking on
   'fullscreen' icon for "cordy" app:
   https://code.google.com/p/chromium/issues/detail?id=475829

These are release blockers and will take some time to investigate, so
revert for this release.

BTW thanks for the great work on this and for the great detailed CL description,
and also answering Fullscreen questions on blink-dev! I hope we can fix all this
in the end.

Thanks for the encouragement! This all is apparently hard to move forward
without breaking stuff, but eventually we'll get there, I trust.
