Original change's description:
> [torque] typed context slot access
> 
> This introduces a new type Slot<ContextType, SlotType> that is used
> for enum values used to access context slots.
> Together with new types for the various custom contexts used in
> Torque, this results in fairly type-safe access to context slots,
> including the NativeContext's slots.
> 
> Drive-by changes:
> - Introduce a new header file to specify headers needed for
>   generated CSA headers, to reduce the amount of includes specified
>   in implementation-visitor.cc
> - Port AllocateSyntheticFunctionContext to Torque.
