Enable high processor vectors/zero page relocation. OS_DynamicArea 20 fixes.

Detail:
  Makefile, hdr/Options - By default enable high processor vectors/zero page relocation for compatible machines, but also allow the components file to override the setting if required
  s/ChangeDyn - Fix OS_DynamicArea 20 to check the correct range for doubly mapped areas, and to correctly localise its error message
Admin:
  Tested on Iyonix


Version 5.35, 4.79.2.268. Tagged as 'Kernel-5_35-4_79_2_268'
