Add `Conditional` wrapper to gtest

This follows an initial proposal for an 'EqIff` matcher. `Conditional` was considered more precise as an EqIff() matcher may suffer from `Iff` not being universally understood.

gtest: Add a flag to only set up/tear down test environments once when repeating

Currently when running a test multiple times using `--gtest_repeat` the global
test environment(s) are set up and torn down for each iteration of the test.
When checking for flakes in tests that have expensive dependencies that are set
up in the test environment (subprocesses, external dependencies, etc) this can
become expensive.

To support finding flakes in tests that fit into this category, where the setup
phase is expensive but each test case is fast, allow callers to specify via
`--gtest_recreate_environments_when_repeating=false` that the test environments
should only be set up once, for the first iteration, and only torn down once, on
the last iteration. This makes running a test with `--gtest_repeat=1000` a much
faster and more pleasant experience.

Make multiple attempts to verify GetThreadCount()

Testing GetThreadCount() is inheritently noisy, as other threads can be started
or destroyed between two calls to GetThreadCount(). This is especially true
under certain analyzer configurations, such as TSAN.

On QNX, pthread is part of libc [1]. There's no separate pthread library
to link.

EXPECT_DEATH() and ASSERT_DEATH() have a switch case where every
possible case is covered. This makes the default case unnecessary
and triggers -Wcovered-switch-default.
Due to these being macros, the lines are expanded in user code and
are thus subject to warnings of the target codebase.

Fixes #3456

Remove -Werror from the CMake compiler flags

We should not force warnings as errors on users.
Sometimes compilers introduce new warnings which
will break builds.

Instead, we manually turn this flag on in our continuous integration
scripts so we can catch these errors, but not force them on our users.

Remove the dependency on Objective C++ in iOS builds.

252ce9c5 introduced the use of
NSTemporaryDirectory() on iOS, which requires Core Foundation, and
Objective C++.

This CL replaces NSTemporaryDirectory() with an equivalent solution
(according to Apple's documentation at [1]) available to C/C++ code.
Avoiding Objective C++ and Core Foundation makes it easier to integrate
googletest in projects that can't use the supplied Bazel build files.
