PageAllocatorInitAligned
Description
Initialize a PageAllocator with a custom alignment floor. Page-backed memory is naturally page-aligned, so requests below the page size are rounded up. Stronger-than-page alignment is best-effort.
Success
Returns a fully-initialised PageAllocator value with the requested alignment floor recorded in base.alignment.
Failure
Cannot fail at macro-expansion time.
