UnitTestFrameworkPkg: Add subhook submodule required for gmock

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4389

Add subhook submodule that is required to hook internal functions
when using gmock.

    https://github.com/Zeex/subhook

Add SubhookLib library class and SubhookLib library instance.
Include the SUBHOOK_STATIC define in the SubhookLib INF file so
it builds as a static library. Also include the SUBHOOK_STATIC
define in SubhookLib.h so all modules using SubhookLib properly
link SubhookLib as a static library.
