BaseTools IA32/X64: prevent .eh_frame sections from being generated
After the recent GNU linker script changes, the following warning is
emitted many times during the OVMF build:
BFD: <...>: warning: Empty loadable segment detected, is this intentional ?
This is caused by the fact that, now that the section layout has changed
somewhat, the .eh_frame section is assigned an ELF segment of its own,
which ends up with no contents at all after we strip the .eh_frame
section from the output. (Note that the program headers that contain the
segment information are completely irrelevant to us since the PE/COFF
conversion does not rely on them.)
Since we only retain the .eh_frame data for external debugging, and not
for things like stack unwinding or generating backtraces at runtime, we
can remedy the situation by passing -fno-asynchronous-unwind-tables on
the GCC command line. This option instructs the compiler to emit the
unwind data into a debug section called .debug_frame instead of into
.eh_frame.

MdePkg/UefiDevicePathLib: Fix RAM Disk Device Path To Text Issue
Perform Left Shift 32 bits of a 32-bit StartAddr[1] and EndingAddr[1]
instead of Right Shift when displaying 64-bit Start and End Address Value.
StartAddr[1] and EndingAddr[1] are already a 32-bit value and it should
perform left shift 32-bit to generate a complete 64-bit value along with
StartAddr[0] and EndingAddr[0] respectively.

MdeModulePkg:Fix the issue FindQuestionFromProgress in SetupBrowserDxe is broken
If the storage of the question is EFI_HII_VARSTORE_BUFFER/EFI_HII_VARSTORE_EFI_VARIABLE_BUFFER,
in SetupBrowserDxe the configuration stings contain uppercase,but HiiDataBaseDxe generates the
ConfigResp string in lowercase,they mismatch,so FindQuestionFromProgress function is broken.
Now convert the configuration string in SetupBrowserDxe to lowercase to fix this issue.

BaseTools GCC: move AutoGen.obj contents to .text section
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.

BaseTools GCC: align start of .data to .text alignment
Now that GenFw honors the ELF section alignment when placing the
PE/COFF sections in the output, the start of the PE/COFF version of
.data will be aligned to the alignment of .text if its alignment is
higher than the default. So duplicate this behavior in the ELF output,
this will make the memory layout of the PE/COFF binary match the
layout of the ELF version more closely.

BaseTools GCC: add unified GCC linker script for all archs and versions
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.

out these values from the various linker scripts, which will allow us
to unify them in a subsequent patch.

BaseTools IA32/X64: move .got contents to the PE/COFF .text section
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.

The .rodata ELF section contains constant non-executable data that
should never be modified by the program itself. Since 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.

BaseTools IA32/X64: remove NOP padding from X86/IA32 GCC linker scripts
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.

ArmVirtPkg: use 'auto' alignment and FIXED placement for XIP modules
Now that GenFw correctly propagates the minimum alignment of the ELF
input sections to the PE/COFF binary, we can simply select 'auto'
alignment in the FDF Rule section instead of tweaking it by hand.
Also add the FIXED FFS attribute to the module types that may execute
in place. This enables a newly added optimization in GenFfs that strips
redundant padding, preventing excessive waste of FV space if the section
alignment is considerable (i.e., 2 KB or 4 KB)
