Bug 39252 - Move host/native JSFunction's NativeFunction onto NativeExecutable.

Reviewed by Geoff Garen.

Currently host functions reuse JSFunction's ScopeChain as storage for their
NativeFunction (the C function pointer to the host function implementation).
Instead, move this onto NativeExecutable. This will allow host functions to
have a scopechain (which will be implemented as a separate patch).
