When MdeModulePkg/Universal/SmbiosDxe is instructed to compose & install
an SMBIOS 3.0 entry point, it keys the Docrev (specification document
revision) field of that structure off of PcdSmbiosDocRev. An upcoming
OvmfPkg patch will have OvmfPkg/Library/SmbiosVersionLib set this PCD
dynamically. Because we use that driver in the ArmVirtQemu.dsc platform,
we must provide a default for the dynamic PCD.

At this point all platforms that use OvmfPkg/SmbiosPlatformDxe in edk2,
namely ArmVirtQemu.dsc and OvmfPkg*.dsc, have been migrated to
SmbiosVersionLib. Therefore SmbiosPlatformDxe itself can forego verifying
QEMU's SMBIOS entry point; if SmbiosVersionLib's validation was
successful, it should just rely on that.
(Note that SmbiosPlatformDxe has a depex on EFI_SMBIOS_PROTOCOL, installed
by SmbiosDxe, containing SmbiosVersionLib, therefore the set/get order of
PcdQemuSmbiosValidated is ensured.)

The LineNumber parameter of the DebugAssert() function has type UINTN.
DebugAssert() passes it to AsciiSPrint() with the %d conversion specifier
at the moment, but %d would require an INT32 argument.
Fix this by casting LineNumber to UINT64, also employing the matching
decimal conversion specifier, %Lu.
(Another possibility would be to cast LineNumber to INT32, but a
UINTN->INT32 cast is not value preserving, generally speaking.)

NT32 has two ranges of memory, each 64MB. The first range is tested
but the second range is not tested. Platform BDS should have code
to use MemoryTest protocol to test the memory so that the second
range of untested memory can be added to the system memory pool.
Without the code SCT MemoryAllocation test case may fail. Because it
firstly use GetMemoryMap to find the biggest free memory descriptor
and then requests to allocate one page more than that biggest free memory.
It expects the allocation fails but actually the DXE core automatically
converts the second range of untested memory to tested and allocate the memory
from the second range.

All AutoGen.obj files consist of global GUID definitions, fixed
and patchable PCDs and other data that is essentially read-only at
runtime but has not been declared as such for various reasons.
By moving these contents to .text we achieve two things:
- global GUIDs and other data items which must be constant for correct
program operation can no longer be modified, for instance, when
running a DXE_RUNTIME_MODULE binary under the OS with the Properties
Table feature for memory protection enabled;
- the .data section becomes smaller, and may be dropped completely for
many XIP modules, which reduces wasted FV space if the PE/COFF section
alignment is large.

This unifies all GCC linker scripts into a single parametrised GCC
linker script that can be used for all GCC versions and architectures.
The two parameters that can be set on the linker command line are:
- PECOFF_HEADER_SIZE, this is a build time property of GenFw, but
its value is different between 32-bit and 64-bit;
- common-page-size, this can be set using -z on the ld command line,
and controls the value of the COMMONPAGESIZE constant when used in
a linker script. This value is used for the minimum section alignment.

Instead of hardcoding the values for the PE/COFF header size and the
section alignment, set them on the linker command line. This factors
out these values from the various linker scripts, which will allow us
to unify them in a subsequent patch.

Move the .got contents to the PE/COFF .text section. This should be
a no-op, since we typically don't generate position independent code
(i.e., using -fPIC). But since the GOT contains variable addresses that
are updated at relocation time only, its contents are best kept in .text
to prevent them from being overwritten inadvertently.

There is no need to pad out the end of a section of the start of
the following section is aligned to the same value. So drop the
redundant ALIGN() statements.

The .rodata ELF section contains constant non-executable data that
should never be modified by the program itself. Since the risk of
inadvertent modification is typically higher than the risk of
inadvertent execution, it makes sense to put this data in the
R-X .text section rather than in the RW- .data section.
So move it there.

The NOP padding in the GCC linker scripts ensures that all empty
regions in the ELF binary are filled with x86 NOP instructions.
There is no upside to doing this: if the CPU ends up executing these
instructions, we have little hope of resuming normal execution of the
program anyway. And having NOP slides in memory only makes it easier
for attackers to launch exploits. So remove them.
