Path2D.addPath should throw if DOMMatrix validation fails

Step two of [1], invokes [2], whose step 1 invokes [3], which says to
throw a TypeError if the dictionary is not "well-formed".

Also remove some dead code in DOMMatrix/DOMMatrixReadOnly and remove few
unused includes of svg_matrix_tear_off.h.
