Fold kvm_util_internal.h into kvm_util_base.h, i.e. make all KVM utility
stuff "public". Hiding struct implementations from tests has been a
massive failure, as it has led to pointless and poorly named wrappers,
unnecessarily opaque code, etc...
Not to mention that the approach was a complete failure as evidenced by
the non-zero number of tests that were including kvm_util_internal.h.

Refactor align() to work with non-pointers and split into separate
helpers for aligning up vs. down. Add align_ptr_up() for use with
pointers. Expose all helpers so that they can be used by tests and/or
other utilities. The align_down() helper in particular will be used to
ensure gpa alignment for hugepages.
No functional change intended.
[Added sepearate up/down helpers and replaced open-coded alignment
bit math throughout the KVM selftests.]

Drop the memslot param(s) from vm_vaddr_alloc() now that all callers
directly specific '0' as the memslot. Drop the memslot param from
virt_pgd_alloc() as well since vm_vaddr_alloc() is its only user.
I.e. shove the hardcoded '0' down to the vm_phy_pages_alloc() calls.
No functional change intended.

Use memslot '0' for all vm_vaddr_alloc() calls when loading the test
binary. This is the first step toward adding a helper to handle page
allocations with a default value for the target memslot.
