arch-arm: Setup TC/ISA at construction time 2nd attempt
This partly reverts commit ec75787aef56665e893d70293bf3a0f93c33bb6a
by fixing the original problem noted by Bobby (long regressions):
setupThreadContext has to be implemented otherswise the GICv3 cpu interface
will end up holding old references when switching TC/ISAs.
This new implementation is still setting up the cpu interface reference
in the ISA only when it is required, but it is storing the
TC/ISA reference within the interface every time the ISA::setupThreadContext
gets called.
