Kasko needs a way to read crash keys from out of process. This API
reuses the functionality of PEImageAnnotationsReader.

The BaseName() was added because system DLLs were being reported by
GetFileVersionInfo()/VerQueryValue() as having major file versions of
6.2 instead of 10.0 on Windows 10 when accessed by full path, but not
by BaseName(). The PEImageReader gets the correct version from the
in-memory images, 10.0.
This trick didn't work on Windows XP, where two copies of comctl32.dll
were found loaded into the process, one with a major file version of
5.82 and the other with 6.0. Giving GetFileVersionInfo() the BaseName()
would result in it returning information from one of these, which would
cause the version to not match when the PEImageReader was looking at the
other.
All of these GetFileVersionInfo() quirks make me glad that we're not
using it anymore (outside of the test).
Because of the version numbers involved (NT 6.2 = Windows 8, where
GetVersion()/GetVersionEx() start behaving differently for
non-manifested applications) and the fact that GetFileVersionInfo()
and VerQueryValue() seem to report 10.0 even with full paths on Windows
10 in applications manifested to run on that OS, the BaseName() thing is
restricted to Windows 8 and higher.

Don't call GetFileVersionInfo(), which calls LoadLibrary() to be able to
access the module's resources. Loading modules from the crashy process
into the handler process can cause trouble. The Crashpad handler
definitely doesn't want to run arbitrary modules' module initializer
code.
Since the VS_FIXEDFILEINFO needed is already in memory in the remote
process' address space, just access it from there.

A few function implementations that were missing, various switches
for functions/functionality that didn't exist on XP, and far too long
figuring out what exactly was wrong with SYSTEM_PROCESS_INFORMATION
on x86 (the "alignment_for_x86" fields).
