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

cs=0023 ss=002b ds=002b es=002b fs=0053 gs=002b efl=00010246
crashy_program!crashpad::`anonymous namespace'::SomeCrashyFunction+0x28:

0:000> !peb
PEB at 7e383000
error 1 InitTypeRead( nt!_PEB at 7e383000)...
Now:
