[jss-expand] Make it produce arrays based syntax

Me and @AleshaOleg are working on last issues with the new css-vendor and we need to vendor prefix compound values e.g. #300. We would need to parse string values otherwise to add prefixes, so now it is easier to deoptimize a bit jss-expand to the jss core array based syntax in order to get the benefits in jss-vendor prefixer.

Example:

transition: ['transform', '1s', 'cubic-bezier(0.23, 1, 0.32, 1)']

should result in

transition: [['transform', '1s', 'cubic-bezier(0.23, 1, 0.32, 1)']]

in order to let vendor prefixer to produce

transition: [['-webkit-transform', '1s', 'cubic-bezier(0.23, 1, 0.32, 1)']]
