In preparation of making the pool code capable of serving allocations
from higher-up bins, update the free path to traverse a candidate page
by following the index of POOL_FREE header instead of duplicating the
carving logic that was used at page allocation time. This allows chunks
to be split into smaller ones, where one can be returned to serve the
allocation, and the other stored in a smaller bin for later use.

The existing linear mapping between allocation size and pool index
does not scale when moving to a 64 KB granularity or beyond. With
a granularity of 64 KB, 2048 (!) bins will be created for each
memory type, each differing 32 bytes in size with the next one.
Instead, introduce an exponential scheme where each bin size is
the sum of the two previous ones.

After fixing the sanity check on the alignment of the runtime regions
in SVN revision #16630 ("MdeModulePkg/DxeMain: Fix wrong sanity check
in CoreTerminateMemoryMap()"), it is no longer possible to define a
runtime allocation alignment that is different from the boot time
allocation alignment.
For instance, #defining the following in MdeModulePkg/Core/Dxe/Mem/Imem.h
will hit the ASSERT () in MdeModulePkg/Core/Dxe/Mem/Page.c:1798
#define EFI_ACPI_RUNTIME_PAGE_ALLOCATION_ALIGNMENT (SIZE_64KB)
#define DEFAULT_PAGE_ALLOCATION (EFI_PAGE_SIZE)
(which is needed for 64-bit ARM to adhere to the Server Base Boot
Requirements [SBBR], which stipulates that all runtime memory regions
should be naturally aligned multiples of 64 KB)
This patch fixes this use case by ensuring that the backing for the memory
pools is allocated in appropriate chunks for the memory type.

The function CoreTerminateMemoryMap() performs some final sanity checks on the runtime regions in the memory map before allowing ExitBootServices() to complete.
Unfortunately, it does so by testing the EFI_MEMORY_RUNTIME bit in the Attribute field, which is never set anywhere in the code.

In CoreFreePages(), the following sequence might break the MemoryMap internal structure:
CoreConvertPages() -> CoreFreeMemoryMapStack() -> AllocateMemoryMapEntry() -> CoreAllocatePoolPages() -> DEBUG_CLEAR_MEMORY()
CoreConvertPages() will call CoreFreeMemoryMapStack() after it adds the freed memory range, so the latter might use the just freed memory range when calling AllocateMemoryMapEntry(). But CoreFreePages() will call DEBUG_CLEAR_MEMORY() after CoreConvertPages(). This might clear up the memory map entry structure.
The fix calls DEBUG_CLEAR_MEMORY() just after freed memory range is added in CoreConvertPages(), which is safe.
