Method to execute testcases early in the boot

A new CONFIG variable has been created that will trigger the
istep dispatcher to start the CXX unit test execution at some
point during the boot rather than waiting until the end.  This
is useful for quick targeted testing and also for early bringup
of new platforms.

CONFIG_EARLY_TESTCASES is the new flag, and it uses
ATTR_EARLY_TESTCASES_ISTEP to determine where in the boot to stop.

Changes were required in several testcases to either skip the
test completely (typically due to not having enough memory) or
to add additional logic to load new support libraries on demand.

The Axone platform has this flag enabled by default to execute
testcases at the end of istep 6.9 (host_gard).
