TT_ADDRESS_* macros were not casting immediate values to UINTN.
This causes shift operations to be off by 32-bits when calculating
addresses above 4GB. Any address above 4GB was being improperly calculated.

Per 2c4b18e ("MdeModulePkg: Add the alignment check for FTW spare area
address and length, and add the check for PcdFlashNvStorageVariableSize
<= PcdFlashNvStorageFtwSpareSize."), FTWDxe refuses to initialize if
spare space base address or size is not aligned to block size.
Depending on configuration, memory for FTWDxe might be dynamically
allocated in PlatformPei. This patch makes sure that the allocated
memory region is aligned.

LoadLinux() is looking at the wrong field for the kernel's EFI handover
protocol flags. It's not currently possible for JumpToUefiKernel() to
ever be called (even accidentally) because BIT2 and BIT3 of
Bp->hdr.load_flags are never set in modern kernels, which means that
control is always transferred to the kernel via the legacy entry point.
Look at the correct field so that the EFI handover protocol is used
whenever it's available.

KVM has a bug that prevents using page tables in the ROM if the ROM
region utilizes the KVM READONLY memory feature. Therefore, we
avoid using page tables stored in the ROM.
Since OVMF doesn't require memory initialization, we just build
page table entries in RAM at 0x80000 very early in the OVMF boot
process. This address is just after the 'temp RAM' which is set
up by the SEC module.
Currently we only set up 4GB of page tables for OVMF's PEI,
but DxeIpl will build identity mapped page tables that cover all
of the available processor physical address space.

Now, Transition32FlatTo64Flat calls SetCr3ForPageTables64
which is located in Ia32/PageTables64.asm.
This change is required so OVMF can replace the code in
Ia32/PageTables64.asm with code that generates page tables in
RAM.
Note: Since this change does not impact the functionality of the
current VTF0 binaries, they are not being updated. The resulting
new binaries were tested to verify there is no regression.
