Fixing CI break caused by previous checkin of the unboxing stubs region to enable the RhGetCodeTarget API:

1) Stubs are still grouped, but by section now. Linker will merge/fold/sort the unboxing stubs by section name.
2) All unboxing stubs are delimited by __unbox_a and __unbox_z symbols
3) __unbox_a and __unbox_z works on all platforms (tested on ProjectN (no regressions verification), ProjectX single and multi-file, Windows CoreRT, Unbuntu CoreRT, and OSX CoreRT)
4) Implementation uses a registration mechanism for unboxing stubs regions, and is multi-file ready for CoreRT (uses a linked list of stub regions)

5) Deleting the R2R section of unboxing stubs since it doesn't work on non-windows. Using extern "C" variables instead.
6) Removing the module enumeration API exposed by the TypeLoaderCallbacks (no longer needed)
