Upstream crashpad_util_test-in-Chromium changes

This upstreams part of
00a0654929.

The gmock_main and gtest_main test launchers detect via a
CRASHPAD_IN_CHROMIUM macro that they are building as part of Chromium,
and use Chromium’s custom test launcher rather than gtest’s
RUN_ALL_TESTS(). This enables parallelism, sharding, and integration
with Swarming.

WinMultiprocess-based tests are not compatible with this test launcher
or with the Swarming test design, and must be disabled when
CRASHPAD_IN_CHROMIUM is set. This is covered by
https://crashpad.chromium.org/bug/205.

CRASHPAD_IN_CHROMIUM is never defined during Crashpad’s own standalone
build, it’s only defined when building in Chromium.
