Subject: BaseMemoryLib: Add missing ASSERT()s for some interfaces.
 BaseTimerLibLocalApic: Add missing EBC architecture support. Note that this
 instance is a dummy one since EBC does not support local APIC timer.
 IoLibDxeCpuIo: Add alignment checking & unsupported width checking by using
 ASSERT()s.
