Some xstate flags are not available in arm64 as it does not have
xstate so we should omit the InitializeXState method on the
`target_cpu = arm64` configuration.

Windows extended contexts must be allocated by InitializeContext2 and
may not be aligned. This means we cannot simply store a struct in
our thread snapshot object, but must instead store enough memory
and alias our struct onto this backing memory.
Note that shadow stack pointers are not yet recorded for the initial
exception - this cannot be determined using LocateXStateFeature in
the capturing process and will be added in a future CL by plumbing
through client messages when a crashed process requests a dump.
See crash/32bd2c53a252705c for an example dump with this baked into
chrome, that has passed through breakpad without breaking it. Local
testing shows this creates valid dumps when built into Chrome, but
that the referenced memory limits may need to be increased to allow
for ssp referenced memory to be included.
See "MANAGING STATE USING THE XSAVE FEATURE SET" Chapter 13 in the
Intel SDM[0]. Many of the offsets and sizes of the extended features
are provided by cpu specific values. We can access these in Windows
using the SDK, and transfer these to the saved extended context
which in turn is understandable by windbg.
Further information is available from AMD Ch. 18 "Shadow Stacks"[1].

In a future CL we will make use of InitializeContext2 which can produce
contexts of varying sizes - this makes the existing use of a union for
wow/x64 contexts no longer feasible.
The context union in process_reader_win is replaced with a (moveable,
copyable) helper struct which currently only knows how to allocate
the replaced WOW or CONTEXT sized unions.
As this field is no longer a member of the Thread struct it cannot
be passed into other functions as a reference, so instead a pointer
is used in these functions.

This change was partially scripted and partially done manually with vim
regex + manually placing the deleted constructors.
The script change looked for destructors in the public: section of a
class, if that existed the deleted constructors would go before the
destructor.
For manual placement I looked for any constructor in the public: section
of the corresponding class. If there wasn't one, then it would ideally
have gone as the first entry except below enums, classes and typedefs.
This may not have been perfect, but is hopefully good enough. Fingers
crossed.
#include "base/macros.h" is removed from files that don't use
ignore_result, which is the only other thing defined in base/macros.h.

Because DumpAndCrashTargetProcess() suspends the process, the thread
suspend count is one too high for all threads other than the injection
one in the thread snapshots. Compensate for this when we detect this
type of exception.

This was done in Chromium’s local copy of Crashpad in 562827afb599. This
change is similar to that one, except more care was taken to avoid
including headers from a .cc or _test.cc when already included by the
associated .h. Rather than using <stddef.h> for size_t, Crashpad has
always used <sys/types.h>, so that’s used here as well.
This updates mini_chromium to 8a2363f486e3a0dc562a68884832d06d28d38dcc,
which removes base/basictypes.h.

Removes the bitness-specific targets in favour of pulling binaries from
the other build directory. This is to avoid the added complexity of
duplicating all the targets for the x86 in x64 build.
Overall, mostly templatizing more functions to support the
wow64-flavoured structures. The only additional functionality required
is reading the x86 TEB that's chained from the x64 TEB when running
as WOW64.
The crashing child test was switched to a manual CreateProcess because
it needs to launch a binary other than itself.

Retrieve context and save to thread context. NtQueryInformationThread
is no longer required (right now?) because to retrieve the CONTEXT, the
thread needs to be Suspend/ResumeThread'd anyway, and the return value
of SuspendThread is the previous SuspendCount.
I haven't handle the x86 case yet -- that would ideally be via
Wow64GetThreadContext (I think) but unfortunately that's Vista+, so I'll
likely need to to a bit of fiddling to get that sorted out. (It's actually
likely going to be NtQueryInformationThread again, but one thing at a
time for now.)

The next big piece of functionality in snapshot. There's a bit more
grubbing around in the NT internals than would be nice, and it has
made me start to question the value avoiding MinidumpWriteDump. But
this seems to extract most of the data we need (I haven't pulled
the cpu context yet, but I hope that won't be too hard.)

The main goal was to get the beginnings of module iteration and retrieval
of CrashpadInfo in snapshot. The main change for that is to move
crashpad_info_client_options[_test] down out of mac/.
This also requires adding some of the supporting code of snapshot in
ProcessReaderWin, ProcessSnapshotWin, and ModuleSnapshotWin. These are
partially copied from Mac or stubbed out with lots of TODO annotations.
This is a bit unfortunate, but seemed like the most productive way to
make progress incrementally. That is, it's mostly placeholder at the
moment, but hopefully has the right shape for things to come.

Mostly size_t <-> unsigned int warnings, but I also had a mistake in
PROCESS_BASIC_INFORMATION, the pids are 32-on-32 and 64-on-64.
The Windows build is still x86 until https://codereview.chromium.org/981333002/.
I don't think I'll bother maintaining the x86 build for now, though we will probably
need it for x86 OSs in the future. It should be straightforward to revive it once we
need it, and have bots to support it.
