[tools] Improve grokdump.py

- Add new address markers:
   T: tagged pointer in the minidump
   C: address into a module in the minidump
   S: pointer into the exception stack in the minidump
   *: other address in the minidump
- Show ASCII decoding of address in dd
- Display potential frame markers on the exception stack:
   00000032212fdae8: 0000000300000000   ........ Smi(3) EXIT frame marker
- Display relative addresses, useful to detect stack frames:
   00000032212fdb68: 00000032212fdb98 S ........  [+6]=00000032212fdcb0 S
   00000032212fdb70: 0000010ff5ca0a84   ........
   00000032212fdb78: 000001064c1fa881   ........
   00000032212fdb80: 0000016a8e52fcb1   ........
   00000032212fdb88: 0000010ff5ca0981   ........
   00000032212fdb90: 0000000d00000000   ........ Smi(13) INTERNAL frame marker
   00000032212fdb98: 00000032212fdcb0 S ........  [+35]=00000032212fdd61 S
