UnitTestFrameworkPkg/SampleGoogleTest: Use EXPECT_ANY_THROW() 

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

Update GoogleTest samples to use EXPECT_ANY_THROW() instead
of ASSERT_DEATH(). ASSERT_DEATH() is a very slow method to
detect an expected ASSERT() condition. Throwing an exception
from ASSERT() and using EXPECT_ANY_THROW() is several orders
of magnitude faster.

Update GoogleTest sample with example of using EXPECT_THROW()
and EXPECT_THAT() to check for more specific ASSERT() conditions
that allow unit test cases to test functions that contain
more than one ASSERT() statement and verify that the expected
ASSERT() is the one that was actually triggered.

Update library mappings so target-based unit tests use
UnitTestDebugAssertLib.inf and host-based unit tests use
UnitTestDebugAssertLibHost.inf
