Simplify CordRepExternal allocation/deallocation.

I think this can save some memory when `Releaser` is empty and when on platforms where alignof(CordRepExternal) < (default `::operator new` alignment).

We no longer need the API requirement that alignof(Releaser) <= (default `::operator new` alignment).

Also remove another static_assert from a TODO in cord_internal.h and fix some warnings about calling std::move on a forwarding reference.
