Berry `math.inf`, `math.isinf()` and fixed json ouput for `inf` and `nan` #21304

Closed s-hadinger closed 5 months ago

Description:

Berry anticipation of https://github.com/berry-lang/berry/pull/421

Add support for math.inf representing the normalized Infinity:

math.inf is infinity (positive), can be set as negative with -math.inf
math.isinf() to test if a value is infinity

For json.dump, values inf, -inf and nan now convert to null which is the best match since inf and nan are not valid json values.

Related issue (if applicable): fixes #21296
