UnitTestFrameworkPkg/UnitTestLib: Add checks for ASSERT()

Browse Source 
REF: REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2801

Add UnitTestDebugAssertLib that provides the UnitTestDebugAssert()
service and the gUnitTestExpectAssertFailureJumpBuffer global
variable.  This NULL library is linked against all host and target
unit test builds.  This guarantees that the UnitTestDebugAssert()
service is available to link against all libraries and modules that
use the DebugLib class.

EDKII_UNIT_TEST_FRAMEWORK_ENABLED must always be defined when
building unit tests so the behavior of the DebugLib ASSERT()
macros can be adjusted to allow the unit test framework to
catch an ASSERT() if it is triggered by a function under test.

/**
If UnitTestStatus is UNIT_TEST_PASSED, then log an info message and return
TRUE because an ASSERT() was expected when FunctionCall was executed and an
ASSERT() was triggered. If UnitTestStatus is UNIT_TEST_SKIPPED, then log a
warning message and return TRUE because ASSERT() macros are disabled. If
UnitTestStatus is UNIT_TEST_ERROR_TEST_FAILED, then log an error message and
return FALSE because an ASSERT() was expected when FunctionCall was executed,
but no ASSERT() conditions were triggered. The log messages contain
FunctionName, LineNumber, and FileName strings to provide the location of the
UT_EXPECT_ASSERT_FAILURE() macro.
@param[in] UnitTestStatus The status from UT_EXPECT_ASSERT_FAILURE() that
is either pass, skipped, or failed.
@param[in] FunctionName Null-terminated ASCII string of the function
executing the UT_EXPECT_ASSERT_FAILURE() macro.
@param[in] LineNumber The source file line number of the the function
executing the UT_EXPECT_ASSERT_FAILURE() macro.
@param[in] FileName Null-terminated ASCII string of the filename
executing the UT_EXPECT_ASSERT_FAILURE() macro.
@param[in] FunctionCall Null-terminated ASCII string of the function call
executed by the UT_EXPECT_ASSERT_FAILURE() macro.
@param[out] ResultStatus Used to return the UnitTestStatus value to the
caller of UT_EXPECT_ASSERT_FAILURE(). This is
optional parameter that may be NULL.
@retval TRUE UnitTestStatus is UNIT_TEST_PASSED.
@retval TRUE UnitTestStatus is UNIT_TEST_SKIPPED.
@retval FALSE UnitTestStatus is UNIT_TEST_ERROR_TEST_FAILED.
