Add a std::make_unique implementation

Some compilers we care about (mostly g++) do not support std::make_unique yet,
but we still want to use it in our codebase to make unique_ptr code more
readable. This commit introduces an implementation derivated from the libc++
code in the Dolphin codebase so we can use it right now everywhere.

Adapted from delroth's pull request.
