  [reland][libc][NFC] split type_traits / utility in separate files (#65314)

`type_traits` and `utility` refer to each other in their
implementations. Also `type_traits` starts to become too big to be
manageable. This PR splits each function into individual files. FTR this
is [how libcxx handles large headers as
well](https://github.com/llvm/llvm-project/tree/main/libcxx/include/__type_traits).

The reland adds two missing functions : is_destructible_v and is_reference_v
