Feature request: Expose Isolate:: SetModifyCodeGenerationFromStringsCallback

[rebu-dt]

See https://v8.github.io/api/head/classv8_1_1Isolate.html#a0e71905d16905c2bf060854a23e2ba75.

This callback is useful for tracking whenever eval/the Function constructor is called and/or disabling code generation from user-provided strings entirely. Note that there was already an attempt to expose this callback, but the PR was closed due to inactivity.
