Add a method to ProcessSnapshotMinidump to expose a similar interface
to ModuleSnapshot::CustomMinidumpStreams(). It's implemented on the
process snapshot here because there is no way to map custom minidump
streams back to a specific module. This allows implementing tests that
inspect custom user streams in minidumps.

Pulls the concrete non-test implementations of MemorySnapshot out into a
template. They were effectively identical on Mac and Linux/Android, and
I was going to have to add another identical one for Fuchsia.
Unfortunately it needs to be a template because of the snapshot merging
template it calls that needs the platform-specific ProcessReader (so it
can't just pass in a base ProcessMemory in initialization instead).
This is used on Mac, Linux, Android, and Fuchsia, but there is still a
Windows implementation (different because its ProcessReader is a bit
different) and a test implementation.

Causes MinidumpMemoryListWriter to merge all overlapping ranges before
writing the MINIDUMP_MEMORY_LIST. This is:
1) Necessary for the Google internal crash processor, which in some
cases attempts to read the raw memory (displaying ASAN red zones),
and aborts if there are any overlapping ranges in the minidump on
load;
2) Necessary for new-ish versions of windbg (see bug 216 below). It is
believed that this is a change in behavior in the tool that made
dumps with overlapping ranges unreadable;
3) More efficient. The .dmp for crashy_program goes from 306K to 140K
with this enabled. In Chrome minidumps where
set_gather_indirectly_referenced_memory() is used (in practice this
means Chrome Windows Beta, Dev, and Canary), the savings are expected
to be substantial.

107fb7631788 added the snapshot library as a dependency of
crashpad_util_test. Most of snapshot has not yet been ported to Linux or
Android. snapshot/capture_memory.cc only supports x86 and x86_64, and
will #error on other CPUs. We don’t build for other CPUs on Mac or
Windows, but we do for Android.
To make it easy to run crashpad_util_test on non-x86 again,
conditionally remove capture_memory.cc on Linux and Android.
crashpad_snapshot_test can be enabled for Linux and Android too by
disabling the CrashpadInfoClientOptions tests which require OS support.
There’s not much left in crashpad_snapshot_test currently for Linux
except for CPUContextX86 and ProcessSnapshotMinidump.EmptyFile, but both

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.
