Subject: feat: allow passing of ObjectTemplate to ObjectTemplateBuilder

https://chromium-review.googlesource.com/c/chromium/src/+/4905829 removed the
ObjectTemplateBuilder constructor which allows passing in an ObjectTemplate.

Electron needs this constructor, namely for gin_helper::Constructible
objects.
