Material PDF: Support RTL languages
Among a number of minor changes to padding and alignmnent, we also switch
viewer-zoom-toolbar to use CSS transitions rather than neon-animation, as
it's much easier to make RTL compatible and more concise code. We also
switch from number input in the page selector, as it does not have
suitable localization support.
Disabling presubmit since it doesn't like paper-tooltip
