Current implementation of looking up toolchain will _insert_ the findings
from vsvarsall.bat to existing path and potentially stuff the variable to
exceed the length of maximal path length accepted by Windows.
This change updated the logic to use the discovered shell varialbes to
replace the existing path, which is desirable in the specific use case.

Wire up the newly added UefiDriverEntrypoint in a way that ties dispatch
of the Ip4Dxe and Ip6Dxe drivers to QEMU fw_cfg variables
'opt/org.tianocore/IPv4Support' and 'opt/org.tianocore/IPv6Support'
respectively.
Setting both variables to 'n' disables IP based networking entirely,
without the need for additional code changes at the NIC driver or
network boot protocol level.

Add a new library that can be incorporated into any driver built from
source, and which permits loading of the driver to be inhibited based on
the value of a QEMU fw_cfg boolean variable. This will be used in a
subsequent patch to allow dispatch of the IPv4 and IPv6 network protocol
driver to be controlled from the QEMU command line.
This approach is based on the notion that all UEFI and DXE drivers share
a single UefiDriverEntryPoint implementation, which we can easily swap
out at build time with one that will abort execution based on the value
of some QEMU fw_cfg variable.

Rebecca reports that builds of AArch64 DSCs that involve PIE linking
when using ELF based toolchains are failing in some cases, resulting in
an error message like
bad definition for symbol '_GLOBAL_OFFSET_TABLE_'@0x72d8 or
unsupported symbol type. For example, absolute and undefined symbols
are not supported.
The reason turns out to be that, while GenFw does carry some logic to
convert GOT based symbol references into direct ones (which is always
possible given that our ELF to PE/COFF conversion only supports fully
linked executables), it does not support all possible combinations of
relocations that the linker may emit to load symbol addresses from the
GOT.
In particular, when performing a non-LTO link on object code built with
GCC using -fpie, we may end up with GOT based references such as the one
below, where the address of the GOT itself is taken, and the offset of
the symbol in the GOT is reflected in the immediate offset of the
subsequent LDR instruction.
838: adrp x0, 16000
838: R_AARCH64_ADR_PREL_PG_HI21 _GLOBAL_OFFSET_TABLE_
83c: ldr x0, [x0, #2536]
83c: R_AARCH64_LD64_GOTPAGE_LO15 _gPcd_BinaryPatch_PcdFdBaseAddress
The reason that we omit GOT based symbol references when performing ELF to
PE/COFF conversion is that the GOT is not described by static ELF
relocations, which means that the ELF file lacks the metadata to
generate the PE/COFF relocations covering the GOT table in the PE/COFF
executable. Given that none of the usual motivations for using a GOT
(copy on write footprint, shared libraries) apply to EFI executables in
the first place, the easiest way around this is to convert all GOT based
symbol address loads to PC relative ADR/ADRP instructions.
So implement this handling for R_AARCH64_LD64_GOTPAGE_LO15 and
R_AARCH64_LD64_GOTOFF_LO15 relocations as well, and turn the LDR
instructions in question into ADR instructions that generate the
address immediately.
This leaves the reference to _GLOBAL_OFFSET_TABLE_ itself, which is what
generated the error to begin with. Considering that this symbol is never
referenced (i.e., it doesn't appear anywhere in the code) and is only
meaningful in combination with R_*_GOT_* based relocations that follow
it, we can just disregard any references to it entirely, given that we
convert all of those followup relocations into direct references.

Add VgaInb() helper function to read vga registers. With that in place
fix the unblanking. We need to put the ATT_ADDRESS_REGISTER flip flop
into a known state, which is done by reading the
INPUT_STATUS_1_REGISTER. Reading the INPUT_STATUS_1_REGISTER only works
when the device is in color mode, so make sure that bit (0x01) is set in
MISC_OUTPUT_REGISTER.
Currently the mode setting works more by luck because
ATT_ADDRESS_REGISTER flip flop happens to be in the state we need.

The current ACPI Reclaim memory size is set as 0x10 (64KiB). The ACPI
table size will be increased if the memory slots' number of the guest
gets increased. In the guest with more memory slots, the ACPI Reclaim
memory size may not be sufficient for hibernation. This may cause
resume failure of the hibernated guest that was booted up with a fresh
copied writable OVMF_VARS file. However, the failure doesn't happen in
following hibernation/resume cycles.
The ACPI_MAX_RAM_SLOTS is set as 256 in the current QEMU. With
ACPI_MAX_RAM_SLOTS, 18 pages are required to be allocated in ACPI
Reclaim memory. However, due to the 0x10 (16 pages) setting, 2 extra
pages will be allocated in other space. This may break the
hibernation/resume in the above scenario.
This patch increases the ACPI Reclaim memory size to 0x12, i.e.
PcdMemoryTypeEfiACPIReclaimMemory is set as 0x12 (18 pages).
