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.

Implement 'Contains(e).Times(n)' matcher modifier which allows to test for arbitrary occurrences including absence with Times(0).

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.

This callsite was previously updated to use ZX_INFO_PROCESS_V2 as a part of a soft transition. It is now time to revert back to `ZX_INFO_PROCESS` (which is now an alias of the former). See fxbug.dev/30751 for more details.

Update the `DescribeTo` signature in the code example at the Writing New Polymorphic Matchers section in gmock_cook_book.
`os` should be a pointer to be consistent with the implementation, which dereference it as `*os`.

Add support to run gtest on Xtensa platform.
This add support to run GTest base test suits on Xtensa
(https://ip.cadence.com/ipportfolio/tensilica-ip) base simulator.
Xtensa only provides libc and some basic operations and does not run an
operating system by default.

This is part of a soft transition over to having ZX_INFO_PROCESS
populate a new struct. See fxbug.dev/30751 for more details.

Print std::u8string, std::u16string, and std::u32string as string literals
Previously, these types were printed as "{ U+123, U+456, U+789 }". However,
printed output in that form is difficult to compare against any literals that
might be defined in code. Instead, just treat these types like std::string
and std::wstring, escaping non-ASCII characters with a hexadecimal escape
sequence.
The tests have also been updated to cover the new functionality: as a bonus,
the tests now also pass with the MSVC toolchain.
Internally, the code has been reorganized to primarily operate in terms of
char32_t, under the assumption that char32_t will always be at least as big
as wchar_t. While that assumption is currently true, perhaps it won't be in
the future...

gtest: Output a canned test suite for environment failures in XML/JSON
This surfaces useful information about the environment failure in a structured form.
As we can see from the updated test, previously unsurfaced information is now present.

Use monotonic time to measure test duration
System time may be updated while a test is running. When this occurs a
duration measured using system time may appear to move backwards, or
jump far forwards.
This change updates the duration measurement to use monotonic time
instead. Timestamps for the test start still use system time.

gtest.cc: Split out functions for printing `TestResult` objects

Explicitly skip tests after fatal global environment setup errors
Previously the tests were all skipped, but the resulting output claimed all
tests passed.
Before:
```
[----------] Global test environment set-up.
<failure message>
[----------] Global test environment tear-down
[==========] 1 test from 1 test suite ran. (83 ms total)
[ PASSED ] 1 test.
[ FAILED ] 0 tests, listed below:
```
After:
```
[==========] Running 1 test from 1 test suite.

Update the custom name example to not use underscores.
The NOTE a few blocks above specifically calls out that test names should not contain undersccores, so probably the example should not suggest using underscores.
