Bindings: Make interface operation properties configurable

Per the Web IDL spec [1]:

4.5.8. Operations: "The property has attributes {
[[Writable]]: B, [[Enumerable]]: true, [[Configurable]]: B
}, where B is false if the operation is unforgeable on the
interface, and true otherwise."

In other words, Object.getOwnPropertyDescriptor(i.p, 'm')
should have configurable: true, except for [Unforgeable]
which is already special-cased.
