SA_EXPOSE_TAGBITS is a Linux >= 5.11 feature that allows si_addr to
contain the upper tag bits. This is a feature that allows signal
handlers to see the full upper address bits on aarch64, which consist of
TBI and MTE nibbles. For MTE, preserving these bits is of significant
importance, as it allows for precise use-after-free and buffer-overflow
diagnosis that's impossible without seeing these bits in the fault
address.
We unconditionally enable this feature on all kernels, as it's ignored
when unsupported (even on older kernels).

1. Linux x86 host, which is a no-op.

However, some Crashpad clients would like to replicate Breakpad's
behavior of allowing uploads while the application is starting up
(before it moves to the foreground).
This CL introdues an optional UploadBehavior enum to
InProcessHandler::StartProcessingPendingReports(), defaulting to the
current behavior of only uploading processed crash reports while the
application is in the foreground.
If the enum is set to UploadBehavior::kUploadImmediately, then
InProcessHandler will start the prune and upload threads regardless
of the application state. (If the application state later transitions
to a non-active state, then InProcessHandler will stop the prune and
upload threads as normal.)

This adds a runtime exception helper (& test module) for Windows and
plumbing to allow the module to be registered by the crashpad client,
and to trigger the crashpad handler. Embedders can build their own
module to control which exceptions are passed to the handler.
See: go/chrome-windows-runtime-exception-helper for motivation.
When registered (which is the responsibility of the embedding
application), the helper is loaded by WerFault.exe when Windows
Error Reporting receives crashes that are not caught by crashpad's
normal handlers - for instance a control-flow violation when a
module is compiled with /guard:cf.
Registration:
The embedder must arrange for the full path to the helper to
be added in the appropriate Windows Error Reporting\
RuntimeExceptionHelperModules registry key.
Once an embedder's crashpad client is connected to a crashpad
handler (e.g. through SetIpcPipeName()) the embedder calls
RegisterWerModule. Internally, this registration includes handles
used to trigger the crashpad handler, an area reserved to hold an
exception and context, and structures needed by the crashpad handler.
Following a crash:
WerFault.exe handles the crash then validates and loads the helper
module. WER hands the helper module a handle to the crashing target
process and copies of the exception and context for the faulting thread.
The helper then copies out the client's registration data and
duplicates handles to the crashpad handler, then fills back the various structures in the paused client that the crashpad handler will need.
The helper then signals the crashpad handler, which collects a dump then
notifies the helper that it is done.
Support:
WerRegisterExceptionHelperModule has been availble since at least
Windows 7 but WerFault would not pass on the exceptions that crashpad
could not already handle. This changed in Windows 10 20H1 (19041),
which supports HKCU and HKLM registrations, and passes in more types of
crashes. It is harmless to register the module for earlier versions
of Windows as it simply won't be loaded by WerFault.exe.
Tests:
snapshot/win/end_to_end_test.py has been refactored slightly to
group crash generation and output validation in main() by breaking
up RunTests into smaller functions.
As the module works by being loaded in WerFault.exe it is tested
in end_to_end_test.py.

This is a reland of 460943dd9a71dc76f68182a8ede766d5543e5341
Original change's description:
> The DoubleForkAndExec() function was taking over 622 milliseconds to run
> on macOS 11 (BigSur) on Intel i5-1038NG7. I did some debugging by adding
> some custom traces and found that the fork() syscall is the bottleneck
> here, i.e., the first fork() takes around 359 milliseconds and the
> nested fork() takes around 263 milliseconds. Replacing the nested fork()
> and exec() with posix_spawn() reduces the time consumption to 257
> milliseconds!
>
> See https://github.com/libuv/libuv/pull/3064 to know why fork() is so
> slow on macOS and why posix_spawn() is a better replacement.
>
> Another point to note is that even base::LaunchProcess() from Chromium
> calls posix_spawnp() on macOS -
> 8f8d82dea0:base/process/launch_mac.cc;l=295-296
The reland isolates the change to non-Android POSIX systems because
posix_spawn and posix_spawnp are available in Android NDK 28, but
Chromium is building with version 23.

This reverts commit 460943dd9a71dc76f68182a8ede766d5543e5341.
Reason for revert: This fails to compile in Chromium Android.
posix_spawn and posix_spawnp are available in Android NDK 28, but
Chromium is building with version 23.
