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
This will make it possible to reuse this code for outputting the "ad_hoc" `TestResult` objects in structured form in XML/JSON.

This is incompatible with compiler caches such as sccache and
clcache. If a project including Google Test specifies /Z7 instead,
building fails with:

Included the string returned by their `name()` member function with the output of `PrintTo`.
Typical use case:
std::unique_ptr<AbstractProduct> product = FactoryMethod();
// Assert that the product is of type X:
ASSERT_EQ(std::type_index{typeid(*product)},
std::type_index{typeid(ProductX)});
Possible output in case of a test assert failure, now including the names of the compared type indices:
> error: Expected equality of these values:
> std::type_index(typeid(*product))
> Which is: 8-byte object <D0-65 54-8C F6-7F 00-00> ("class ProductY")
> std::type_index(typeid(ProductX))
> Which is: 8-byte object <40-64 54-8C F6-7F 00-00> ("class ProductX")

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 tear-down
[==========] 1 test from 1 test suite ran. (83 ms total)
[ PASSED ] 1 test.

After:
```

Update stale links to `gmock_cook_book.md`.
I'm a new googletest user and found these links broken when reading the documentation.

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.
