Add WTF::Vector::emplaceAppend()

Add WTF::Vector::emplaceAppend()

The introduced 'emplaceAppend()' method provides more efficient code path when a new object instance requiring multiple constructor arguments is appended to a vector.

Note: the existing 'append()' method is already implicitly emplacing new items for a single constructor argument case.
