[JSC] Fix `ToIndex(value)` to Align with TC39
https://bugs.webkit.org/show_bug.cgi?id=298629
Reviewed by Yusuke Suzuki.
This patch fixes `ToIndex(value)` implementation to align with TC39 [1].
This fix indirectly corrects functions that rely on `ToIndex(value)`,
such as `BigInt.asUintN`[2], `BigInt.asIntN`[3] and more.
