KVM: selftests: Expose align() helpers to tests
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.]
