Idan Horowitz 3e909c0c49 Kernel: Remove double-counting of allocated pages in AnonymousVMObject 
When constructing an AnonymousVMObject with the AllocateNow allocation
strategy we accidentally allocated the committed pages directly through
MemoryManager instead of taking them from our m_unused_physical_pages
CommittedPhysicalPageSet, which meant they were counted as allocated in
MemoryManager, but were still counted as unallocated in the PageSet,
who would then try to uncommit them on destruction, resulting in a
failed assertion.

To help prevent similar issues in the future a Badge<T> was added to
MM::allocate_committed_user_physical_page to prevent allocation of
commited pages not via a CommittedPhysicalPageSet.
