style: Remove NS_AUTHOR_SPECIFIED_PADDING

Browse source 
There's only one meaningful usage of it, which is to disable native
appearance of the <input type=range> (the windows native theme is no
longer exposed to content).

<input type=range> is inconsistent with every other native widget, which
only disables native appearance if the author specifies backgrounds or
borders. So make it match literally all other widgets and simplify a bit
the code.

We had no tests for this special behavior, let me know if you think it's
worth adding one (but I don't feel very strongly about it).
