UnitTestFrameworkPkg/UnitTestDebugAssertLib: Add GoogleTest support

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4683

Add an C++ implementation of UnitTestDebugAssert() API for
host-based environments. GoogleTest based environments throw
a C++ exception of type std::runtime_error when an ASSERT() is
triggered with a description that contains the filename, line
number, and the expression that triggered the ASSERT().
