Scripting: ScriptFactory not required by compile (#50344) (#50392) 

Avoid backwards incompatible changes for 8.x and 7.6 by removing type
restriction on compile and Factory.  Factories may optionally implement
ScriptFactory.  If so, then they can indicate determinism and thus
cacheability.

**Backport**
