Bug 1639030 - Part 1: Update with_update and after_update patches. r=bobowen

This commit updates files under security/sandbox/chromium-shim/patches/
to prepare our codebase for Chromium sandbox update.  See patch files for
the details of each patch.

This also removes the following patches from with_update no longer needed.

1) update_chromium_linux_x86_syscalls.patch is included in
   b4f3df4e77
2) ifdef_out_ApplyMitigationsToCurrentThread.patch cannot be used because
   we use ApplyMitigationsToCurrentThread since the following commit.
   4bed2eb502
3) mingw_base_win_get_caller.patch is included in
   d8b73eb8f0
4) fix_incorrect_int_use_in_Kernel32BaseVersion.patch is fixed by
   https://hg.mozilla.org/mozilla-central/rev/dc9d71fb3bac807a37dbfba35d609ac4ffff1980
5) revert_removal_of_AlterEnvironment_on_Windows.patch is altered by adding
   environment_internal.h/cc as a different commit.
6) mingw_undefine_MemoryBarrier.patch is no longer needed as
   base::subtle::MemoryBarrier was removed by
   bdbaaf4e7e
7) public_siginfo_fields.patch is included in
   6bd491daaf

screwed it up.

Bug 1611565 - Cherry-pick upstream patch to use public siginfo_t fields r=gcp
Upstream patch:
https://chromium.googlesource.com/chromium/src.git/+/6bd491daaf28a8281136931133504c23a18f819f%5E%21/#F0
_sifields is a glibc-internal field, and is not available on musl
libc. Instead, use the public-facing fields si_call_addr, si_syscall,
and si_arch, if they are available.

Add BrokerServicesBase::IsSafeDuplicationTarget. r=bobowen
This is basically a revert of chromium commit 996b42db5296bd3d11b3d7fde1a4602bbcefed2c.
This patch adds BrokerServicesBase::IsSafeDuplicationTarget and
BrokerServicesBase::AddTargetPeer using the new ProcessTracker introduced by
https://chromium.googlesource.com/chromium/src.git/+/3d8382cf9dd44cf9c05e43e42c500f4825e1fed8
We need these methods for HandlePolicy which is added as a different patch.
Chromium used to have AddTargetPeer and IsActiveTarget, but removed by
the following commits because they were no longer used in Chromium.
https://chromium.googlesource.com/chromium/src.git/+/996b42db5296bd3d11b3d7fde1a4602bbcefed2c

Reinstate sandbox::TargetServices::BrokerDuplicateHandle. r=bobowen
This basically reverts chromium commit 569193665184525ca366e65d0735f5c851106e43.
This patch reverts the commit removing sandbox::TargetServices::BrokerDuplicateHandle
and applies the new IpcTag type.
