Scott Graham 0758dbde9a win: Save contents of PEB to minidump to start making !peb work
This makes the basics of !peb work in windbg, however, pointed-to things
are not yet retrieved. For full functionality, a variety of pointers in
the PEB also needs to be walked and captured.

e.g.

Previously:

0:000> .ecxr
eax=00000007 ebx=7e383000 ecx=c3f9a943 edx=00000000 esi=006d62d0 edi=003c9280
eip=00384828 esp=005bf634 ebp=005bf638 iopl=0         nv up ei pl zr na pe nc
cs=0023  ss=002b  ds=002b  es=002b  fs=0053  gs=002b             efl=00010246
crashy_program!crashpad::`anonymous namespace'::SomeCrashyFunction+0x28:
00384828 c7002a000000    mov     dword ptr [eax],2Ah  ds:002b:00000007=????????
0:000> !peb
PEB at 7e383000
error 1 InitTypeRead( nt!_PEB at 7e383000)...

Now:

0:000> .ecxr
