Update apf_disassembler and apf_run to print instruction size

This commit updates the apf_disassembler and apf_run utilities to also
print the size of each instruction. This enhancement makes it easier to
analyze the disassembled output and optimize program size for improved
bytecode efficiency.

Example apf_disassemble output:

(   5) 3276: jgt         r0, 0x12c, 3452
(   2) 3281: li          r0, 6
(  12) 3283: jbsne       r0, 0x9, 3452, f434f06452fe86dd60

Example apf_run output:

      R0       R1       (size)    PC  Instruction
-------------------------------------------------
       0        0       (   4)   19: debugbuf    size=2766
       0        0       (   2)   23: ldm         r0, m[15]
       0        0       (   2)   25: stdw        counter=6, r0
