96f687b567 win: remove unused fields from CrashpadInfo
These were made unnecessary after changing how registration works, but I
forgot to actually delete them from CrashpadInfo.

f21b740171 asan: Don’t pad the CrashpadInfo struct with a red zone
MachOImageReader::GetCrashpadInfo() expects the CrashpadInfo struct to
be the only thing in a __DATA,__crashpad_info section, and enforces this
by checking that the section’s size matches the size declared in the
struct’s size_ field.

Under AddressSanitizer, a red zone follows the structure. While not
reflected in the size of the structure, it is reflected in the size of
the section, causing MachOImageReader::GetCrashpadInfo() to reject the
CrashpadInfo on the assumption that something else is present in the
section.

By specifying an alignment greater than the minimum red zone size of 32
bytes, red zone generation can be suppressed.

a691448ffb win: Implement exception snapshot
Refactor some of the NT internals helpers and cpu_context to share
between the thread and exception snapshot code.

Add test that runs crashing child and validates the exception in the
snapshot.

1a770c8237 Implement more of CrashpadClient on Windows
SetHandler connects to RegistrationServer as a handler,
and catching an exception writes EXCEPTION_POINTERS to
CrashpadInfo.

69d135acda win: make CrashpadInfo retrievable
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.

9b7ff0ea5a Allow exception forwarding to the system’s native crash reporter to be
disabled.

ClientInfo::set_system_crash_reporter_forwarding() can be used to
disable forwarding. The first module that is found with a non-default
value in this field will dictate whether forwarding is enabled or
disabled. It is possible to enable or disable reporting with this call,
as well as reset it to default, which will allow later modules a chance
to influence the behavior.

ClientInfo::set_crashpad_handler_behavior() is also provided, which can
be used to disable Crashpad’s handling of the exception. Most users
should not call this, but should use Settings::SetUploadsEnabled()
instead.

b0cf01978d win: Get client/crashpad_info.cc to compile
Just avoid the Mac-specific __attribute__ tagging for now. There will need
to be some Windows-specific pragmas added here once the reader has been
written.
