NetworkPkg: PxeBcDhcp6GoogleTest: Fix Stack Smashing Unit Test
PxeBcDhcp6GoogleTest's MultipleDnsEntries test started to fail
with stack cookies added for host applications. Debugging this
showed that the test was attempting to copy two UINT16s to a
UINT8 Data[1] array allocated on the stack. This was moved to
a heap based allocation for a UINT32 to accommodate the proper
size. After this fix, the unit test passed with stack cookies
enabled.

UnitTestFrameworkPkg: Move common includes to their own file
Previously, the UnitTestFrameworkPkgHost.dsc.inc included the entire
UnitTestFrameworkPkgTarget.dsc.inc file. This is unnecessary for
most configurations, so copy the relevant common components to a
separate file.
This is required for stack cookies so that we can have stack
cookies on target based test apps but not on host base test apps.

MdePkg: Add Stack Cookie Interrupt Vector PCD
This patch adds a PCD allowing a platform to specify
the interrupt vector to trigger on a stack check
failure. On x86, this is an offset into the IDT.
On ARM/AARCH64, this triggers a software interrupt
that can be decoded to indicate this was a stack
check failure.

MdePkg: Create Stack Check Null Libs
Add Null libs for Stack Check and Stack Check Failure Hook Lib that
allow a platform to opt out of stack checks and the stack check failure
hook lib.
StackCheckLib allows implementation (or in this case null implementation)
of stack checks on binaries. There is a Host Application specific version
of this null lib because MSVC host applications must not be linked against
our lib (so the file here is a no-op but that doesn't cause the build
system to fail the build for not building a file for MSVC) as it links
against the MSVC C runtime lib that provides the stack cookie definitions.
GCC host applications do not link against such a C runtime lib and must
be linked against our version.
StackCheckFailureHookLib lets a platform do custom functionality when a
stack check failure occurs (such as log it to a platform defined
mechanism). The null lib simply returns.

Log Message:

MdePkg: Create Stack Check Lib
StackCheckLib contains the required functionality for initializing
the stack cookie value, checking the value, and triggering an interrupt
when a mismatch occurs. The stack cookie is a random value placed on the
stack between the stack variables and the return address so that
continuously writing past the stack variables will cause the stack cookie
to be overwritten. Before the function returns, the stack cookie value
will be checked and if there is a mismatch then StackCheckLib handles the
failure.
Because UEFI doesn't use the C runtime libraries provided by MSVC, the
stack check code is written in assembly within this library. GCC and
Clang compilers have built-in support for stack cookie checking, so this
library only handles failures.

BaseTools: Update Stack Cookie Logic
This patch updates the GenC logic to generate a random stack cookie value
for the stack check libraries. These random values improve security
for modules which cannot update the global intrinsics.
If the stack cookie value is randomized in the AutoGen.h file each
build, the build system will determine the module/library must be
rebuilt causing effectively a clean build every time. This also makes
binary reproducibility impossible.
This patch updates the early build scripts to create 32 and 64-bit JSON
files in the build output directory which each contain 100 randomized
stack cookie values for each bitwidth. If the JSON files are already
present, then they are not recreated which allows them to be stored and
moved to other builds for binary reproducibility. Because they are in
the build directory, a clean build will cause the values to be
regenerated.
The logic which creates AutoGen.h will read these JSON files and use a
hash of the module GUID (the hash seed is fixed in Basetools) to index
into the array of stack cookie values for the module bitwidth. This
model is necessary because there isn't thread-consistent data so we
cannot use a locking mechanism to ensure only one thread is writing to
the stack cookie files at a time. With this model, the build threads
only need to read from the files.
