SVGElement::parseAttribute resolves property via property map (Step 2.6)

SVGElement::parseAttribute resolves property via property map (Step 2.6)

SVGAnimatedOrder is introduced to handle parse errors for SVGFEConvolveMatrixElement's orderAttr in setBaseValueToString.

This is to replace the existing |SVGElement::parseAttribute| implementation,
but as there are many callers, we would like to proceed this incrementally.
a) Introduce |SVGElement::parseAttributeNew| *LANDED*
b) Convert all overrides |SVGElement::parseAttribute| to
   a |parseAttributeNew| call. <-- This patch
c) Replace existing |parseAttribute| with |parseAttributeNew|, and remove all
   overrides simply calling |parseAttributeNew|

This patch is (b).
