Some users of crashpad load and unload the dll that hosts
crashpad code. crashpad registers a vectored exception handler
to help collect heap corruption crashes. If the dll is
unloaded this handler might still be called.
This CL adds a scoped handler for such registrations and
uses it on Windows crashpad client. To allow this to
be stored, RegisterHandler() on the client needs to move
onto the client object from being a helper function.

Previously, StartProcessingPendingReports() only started the prune and
upload threads if it thought the application was actively running in
the foreground.
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.

Change the NSException handler generated from the Objective-C exception
preprocessor to not used the cached intermediate dump writer and
not use the same first-exception-wins logic. This is useful because the
Objective-C exception preprocessor is imperfect and may generate
intermediate dumps that are not followed by process termination.

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
