cpu: Add getSendFunctional to ThreadContext
Some cpu context has private memory, for example the tightly coupled
memory(TCM) in Cortex-M arch. The memory request should be initiated
from the aspect of ThreadContext instead of the aspect of cpu. We add
getSendFunctional to ThreadContext and call to getSendFunctional of cpu
as default implementation.
