This patch adds wrapper headers for `<functional>`
and a few others which is required to support
`<functional>`.

The basic idea is to make template functions
defined in these headers host device by pragmas.

Since this only works for libc++. The code is conditioned
for libc++ only. For libstdc++ it is NFC.
