Offload the programming interface info from part->flags to part->prog_modes

Browse Source 
flags now just hold parameters of the JTAG interface and some secondary
serial, parallel, pseudo parallel info. This separation brings clarity. It
used to be hard to augur whether a part has an ISP interface:

   (part->flags & (AVRPART_HAS_PDI | AVRPART_AVR32 | AVRPART_HAS_TPI
    | AVRPART_HAS_UPDI)) == 0 && (part->flags & AVRPART_SERIALOK) != 0

or had HVSP or HVPP capability, for that matter. Now it is just, eg,

  part->prog_modes & PM_ISP
  part->prog_modes & PM_HVPP
