Oliver Smith-Denny	e63cdeebb8	MdePkg: Add StackCheckLib Library Class ... StackCheckLib defines the interface between a compiler and the stack checking code. It is being converted from a NULL library class to an actual library class to make it easier to use for a platform and be easier to define the expected interface with a compiler, so if there is a compiler change it can be tracked and caught.

Taylor Beebe	ac43bbacde	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.
