[kernel] Run global constructors

Look up the global constructor list that the linker outputs, and run
them all. Required creation of the `kutil::no_construct` template for
objects that are constructed before the global constructors are run.

Also split the `memory_initialize` function into two - one for just
those objects that need to happen before the global ctors, and one
after.
