fix: use ESP partition type for UEFI boot detection

- Partition 2 type GUID changed from msftdata (EBD0A0A2) to ESP
  (C12A7328) in GUI installer, CLI partition resizer, and shell
  installer. UEFI firmware only scans ESP-type partitions for
  BOOTX64.EFI.
- GPT is now the default partition style (MBR via -m flag)
- Secure Boot default changed to OFF
- Fix PATH using $PWD instead of $OLDDIR in Hiperiso2Disk.sh
- Remove unused g_WindowsDataPartGuid dead code from partresize.c
