Correct and complete dependency sets after 74b411d38c48513a125e67e049aca55452b9e855

Summary

Prior to this change the __support_cpp_array_ref target's only dependency was libc_root.
but it #includes "TypeTraits.h" and Array.h for that matter.

These dependencies matter when building in distributed build systems and the relevant
files must be know for the distributed build to ship them to the executor.

Sounds plausible to me - once the pre-merge checks come back green.
