style: Remove Options from TransformOperation.

Browse source 
This may or may not be part of the plan to get rid of nsCSSValue ;)

Option is not usable via FFI, and they should not be needed (we should be
following the shortest serialization principle instead). These patches also do
that, which matches the other transform properties. I think that slight change
is fine, if we can make it work, and consistent with other properties.

Alternative is adding more TransformOperation variants or such, which I rather
not do.
