Make native_shared_libs configurable

So that you can use selects with it.

This cl also creates a ResolvedApexNativeDependencies to represent
a merged and evaluated set of ApexNativeDependencies. Previously other
properties added their own "resolved" versions individually, but I
think it's better design for the property structs to remain unchanged,
so I created a new non-property struct to contain the resolved values.
Immutable property structs is one of the things we want to add for
performance (removing property struct copies).
