Currently, ProcessMemory is only implemented for Linux and Fuchsia.
Implement the interface for Windows as well and re-factor tests to
support it, mostly this consists of using a new ScopedGuardedPage class
instead of ScopedMmap in the ProcessMemory tests.

pthread_threadid_np() reports an incorrect thread ID after fork() on
macOS 10.14 (“Mojave”). See https://openradar.appspot.com/43843552. As a
workaround, use thread_info(…, THREAD_IDENTIFIER_INFO, …).
This uses MachThreadSelf(), which in turn uses pthread_mach_thread_np(),
which does not suffer from the same bug. As an alternative,
base::mac::ScopedMachSendRight(mach_thread_self()) could be used.

The desc value in the note is now the offset of CRASHPAD_INFO_SYMBOL
from desc.
Making this note writable can trigger a linker error resulting in
the binary embedding .note.crashpad.info to be rejected by the
kernel during program loading.
The error was observed with:
GNU ld (GNU Binutils for Debian) 2.30
clang version 4.0.1-10 (tags/RELEASE_401/final)
Debian 4.17.17-1rodete2
When the note is made writable, crashpad_snapshot_test contains two
PT_LOAD segments which map to the same page.
LOAD 0x0000000000000000 0x0000000000000000 0x0000000000000000

Executing this binary with the execv system call triggers a segfault
during program loading (an error can't be returned because the original

I suspect (I haven't set up a debuggable kernel) the failure occurs
while attempting to map the second load segment because its virtual
address, 0x258, is in the same page as the first load segment.

The linker normally produces consecutive load segments where the second

We were still generating gyp build files on the bots, and then using the
GN build. There's some not-working logic in gyp to find the hermetic
Xcode SDK that the new bots are using, so just avoid generating the gyp
build now, since we're not using it anyway.
(My understanding is that the Android build uses
build/gyp_crashpad_android.py instead not build/gyp_crashpad.py. But
there's no Android bots in any case, so it shouldn't be a problem for
that.)

The actual amount varies, but is typically 40 bytes for 32-bit android

64 bytes for linux system libraries (on my machine), but so far they're
