* 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.
- add `minimum_length` to enforce array length validation
- add `JS_NewDate()` API
- add `[Symbol.toStringTag]` property in the global object
- simplify `string_get_milliseconds`
- support more timezone abbrevs using `string_get_tzabbr` and array
- add `memcpy_no_ub` that accepts null pointers for 0 count
- prevent 0 length allocation in `js_worker_postMessage`
- use safer test for `int` value in `JS_NewFloat64`,
`JS_ToArrayLengthFree` and `js_typed_array_indexOf`
If you want to extend a built-in class you need it's class ID and there
is no robust way to get that without this accessor.
* add JS_INVALID_CLASS_ID constant for invalid class ID.
