Add JS_StrictEq(), JS_SameValue(), and JS_SameValueZero() (#264)

Browse Source 
* add `JS_StrictEq()`, `JS_SameValue()`, and `JS_SameValueZero()` all accepting `JSValueConst`
* make `js_strict_eq` accept `JSValueConst`, remove uses of this function internally and replace them with
`js_strict_eq2` instead.
