fix: javascript heap OOM is not raised (#45895)

fix: javascript heap oom is not raised in node::OOMErrorHandler

node::OOMErrorHandler terminates the process directly without raising an
oom exception. To fix it, set an oom handler into node from electron.

+Subject: feat: add oom_error_callback in node::IsolateSettings
+
+Expose v8::OOMErrorCallback to allow setting OOM error handler outside Node.js
+
+As described in this issue https://github.com/electron/electron/issues/45894,
+Electron fails to capture js heap oom because node::OOMErrorHandler just
+terminates the process without raising an exception.
+
+To fix this issue, provide the interface oom_error_callback to enable a
+custom oom error callback set from Electron.
