arch-arm: Fixed error in choosing vector offset

The old code chose vector offset associated with exceptions taken
to EL3 by incorrectly using "from64", which is associated with the
exception level where the exception was taken from. However, the
offset should depends on the ISA of the lower EL and not of the
starting EL itself, as specified in ARM ARM. This patch corrects
this by implementing the method in AArch64.TakeException in ARM ARM.
