KGDB fixes for amd64 and aarch64.

- Update the amd64 kernel support to recognize mchk_calltrap as a
  trapframe generator.
- Remove some unneeded headers from fbsd-kld.c.
- Various fixes to get stack traces working for aarch64 kernels:
  - Map the LR register from the PCB to PC instead of LR.
  - Skip the PC register from the PCB as it isn't initialized to anything.
  - Correct the register cache map for the PCB.  The old one had the
    offsets of pcb_sp and pcb_pc reversed.
  - Don't map all of the saved general purpose registers in a
    trapframe to X1 rather than X0 .. X29.
  - Use correct name for el0 trapframe entry points.
