Change ComputedStyle::setUnique to take bool parameter.
Currently setUnique() takes no arguments and sets the corresponding
nonproperty flag to be true. However, this is different to the
traditional setters of property fields, where they set the field to an
argument value. Instead of handling setUnique as a special case in the
generator, we change setUnique to a normal setter that takes a boolean
parameter. This decision was discussed in crrev.com/2667543002.
This is prework for generating 'unique'.
