bitbake: toaster: update Task classification fields

This patch updates the task classification fields (outcome, etc)
as to

* Changes outcome names from SSTATE to CACHED and
from EXISTING to PREBUILT

* NoExec tasks now recorded as Not Executed / script type NA instead
of Executed / script type NOEXEC. Script type NOEXEC is deleted.

* SetScene tasks do not get order numbers

* New task method that returns a QuerySet for setscene tasks related
to this task: Task.get_related_setscene()

* New custom TaskManager that allows searching for setscene tasks
related to a certain task: Task.objects.related_setscene(task)
