Add a hook that allows for ahead-of-time compiled functions

Use the unused field in the CachedUnit structure provided by qmlcachegen
to allow for providing function pointers for functions and bindings that
are compiled ahead of time.

Provided is the pointer into an array that is terminated with a {index:
0, functionPtr: nullptr} entry. The array index field in each array
entry allows for gaps.
