6265674c98 Migrate to NOTREACHED()
This was tested locally by adding "-Wunreachable-code-aggressive" after
making NOTREACHED() [[noreturn]] in mini_chromium and then getting that
to compile.

6af42bc0b2 Use NOTREACHED_IN_MIGRATION()
This was generated by replacing "  NOTREACHED()" with
"  NOTREACHED_IN_MIGRATION()" and running git cl format.

This prepares for making NOTREACHED() [[noreturn]] alongside
NotReachedIsFatal migration of existing inventory.

ef8a063055 Fuchsia: Propagate failure to initialize exception snapshot
If the process' threads can't be read, then the cpu context object won't
be able to be initialized.

Previously, the process snapshot always assumed that the context would
be filled out, as there was no error returned, which could result in
later checks failing.

Return an error from the exception snapshot's initialization so that
process snapshot can correctly handle failure to initialize.

b71f61f8e3 fuchsia: Defer initialization of memory map
This allows partial reading of the current process (e.g. modules or
CrashpadInfo), even though the memory map read (and so thread retrieval)
will fail if ProcessSnapshotFuchsia is used on the current process.

This is a follow up to
db6f51d3fc
which broke the CrashpadInfoClientOptions.* tests.

8b6f158d20 fuchsia: Include address space information in process snapshot
This plumbs some of the ZX_INFO_PROCESS_MAPS information out into
MINIDUMP_MEMORY_INFO. The mapping loses some information that Zircon
provides, and some of the data that Windows would provide isn't
available (for example, AllocationProtect). But this gives a general
idea of the memory layout of the process to check for bad pointers, etc.
when inspecting crashes.

d9bf38f39c fuchsia: More fixes to get a basic minidump written
With this `generate_dump <somepid>` generates a valid and somewhat
plausible (but still quite incomplete) minidump.

As an example, on a running Fuchsia system, `ps` reported the pid of
"netstack" as 6062, followed by `generate_dump 6062`, copy minidump.6062
to host, and run Breakpad's minidump_dump on the generated dump file,
resulting in:
https://gist.github.com/sgraham/24e4ba1af968219d7c154bb0fba43925

This looks roughly correct in that it has a bunch of threads (without
much data) and a reasonable looking module list.
