Reintroduce JSValueConst and add a JS_CHECK_JSVALUE build mode that catches reference counting bugs by making JSValue and JSValueConst different types. The *vast* majority of this commit is rote work to make our own sources compile cleanly in said mode. Refs: quickjs-ng#944

Damn! I hope you found a way not to type all that by hand...

Great work, thank you!
I've skimmed through the diff and then the public API, some suggestions (I have no idea how to do this through GH UI, sorry...):
- JS_MarkValue, JSClassFinalizer, JSClassGCMark, and JS_IsPromise take a JSValueConst for val
- JS_PromiseResult takes JSValueConst for promise
- JS_IsLiveObject, JS_GetOwnPropertyNames take JSValueConst for obj
- JS_IsEqual, JS_IsStrictEqual, JS_IsSameValue, JS_IsSameValueZero take JSValueConst for both params (they all dup the params first)
- JS_GetPrototypePrimitive returns a JSValueConst

@bnoordhuis Do you want me to hold on the release until this lands? It does seem worthy. |

Yes, please. I'll incorporate @bptato's suggestions where possible. |

Not fully done yet - still some 400 warnings left to fix 🤦 - but already uncovered a RC bug injs_date_setYear.Done. Caught a further two or three RC buglets.
