Jian J Wang 6cf0a677a9 MdeModulePkg/DxeCore: Fix issues in Heap Guard
One issue is that macros defined in HeapGuard.h

    GUARD_HEAP_TYPE_PAGE
    GUARD_HEAP_TYPE_POOL

doesn't match the definition of PCD PcdHeapGuardPropertyMask in
MdeModulePkg.dec. This patch fixed it by exchanging the BIT0 and BIT1
of them.

Another is that method AdjustMemoryF() will return a bigger NumberOfPages than
the value passed in. This is caused by counting twice of a shared Guard page
which can be used for both head and tail Guard of the memory before it and
after it. This happens only when partially freeing just one page in the middle
of a bunch of allocated pages. The freed page should be turned into a new
Guard page.
