Add support for CSSValue->CSSSimpleLength when it is a percentage.

Add support for CSSValue->CSSSimpleLength when it is a percentage.

Incidentally fix issue where percent-typed CSSSimpleLengths were
returning "%" instead of "percent" from type().

Also added a test that you can't set value or type, as setting type
was removed in https://codereview.chromium.org/2373233002
