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...

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")
With help from Krystian Kuzniarek.
Print unique_ptr/shared_ptr recursively.
Given that they are smart pointers, it is unlikely that the inner object is
invalid.

Improve lookup of operator<< for user types
Without this fix, trying to use this class with googletest
struct Foo {};
template <typename OutputStream>
OutputStream& operator<<(OutputStream& os, const Foo&) {
os << "TemplatedStreamableInFoo";
return os;
}
results in an ambiguity error between the class' operator<< and the
operator<< in gtest-printers.h removed in this CL.
This fix also enables implicit conversions to happen, so that e.g.
we will find the base class operator<< if a subclass has no
operator<< of its own.

Detection of string_view type (whether it's std or Abseil)
is done in googletest/include/gtest/internal/gtest-port.h
with GTEST_INTERNAL_HAS_STRING_VIEW.
Adds support for printing the types char8_t, char16_t, and char32_t
This changes prints these types as Unicode code points. It is possible
that there is a better way of printing these types, but that change is
more complex, and the format in which Googletest prints these types is
subject to change if someone implements a better way of printing them.
This fixes the C++20 build, which removed support for printing these types.

Remove support for "global" ::string and ::wstring types.
This support existed for legacy codebases that existed from before namespaces
where a thing. It is no longer necessary.

Now that googletest has moved to C++11, it should no longer
use NULL or 0 for the null pointer. This patch converts all
such usages to nullptr using clang-tidy.
This prevents LLVM from issuing -Wzero-as-null-pointer-constant
warnings.

Because in `std::tr1::tuple_element` the first template parameter should be of type int (https://gcc.gnu.org/onlinedocs/libstdc++/libstdc++-html-USERS-4.4/a00547.html), but the code inserts a size_t, the first template parameter should be casted to int before, to get rid of the following errors:
googletest-src/googletest/include/gtest/gtest-printers.h:957:60: error: conversion from ‘long unsigned int’ to ‘int’ may change value [-Werror=conversion]
