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.
