base: remove local capability from generic base

Browse Source 
* Instead of using local capabilities within core's context area implementation
  for stack allocation/attachment, simply do both operations while stack gets
  attached, thereby getting rid of the local capabilities in generic code
* In base-hw the UTCB of core's main thread gets mapped directly instead of
  constructing a dataspace component out of it and hand over its local
  capability
* Remove local capability implementation from all platforms except Linux
