Due to confusion arisen from "iff" standing for "if and only if",
this commit uses the latter.

Per the MSVC documentation the warning is new as of Visual Studio 2017,
version 15.8.
https://docs.microsoft.com/en-us/cpp/error-messages/compiler-warnings/c5046?view=vs-2019
GTest users building on MSVC 2015 or older versions of 2017 will, when
C4616 is enabled, see a warning like:
[...]gtest-matchers.h(53): error C2220: warning treated as error - no 'object' file generated
[...]gtest-matchers.h(53): warning C4619: #pragma warning: there is no warning number '5046'
Guard the mention of 5046 by an _MSC_VER check. VS2017 15.8 corresponds
to an _MSC_VER of 1915.

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.

Fix matcher comparisons for std::reference_wrapper.
The googletest docs indicate that std::reference_wrapper should be used to for
objects that should not be copied by the matcher (in fact, the ByRef() function
is basically the same as a call to std::cref).
However, for many types (such as std::string), the overloaded operator== will
not resolve correctly. Specifically, this is problematic if operator== depends
on template argument deduction, where the same type is named on LHS and RHS.
Because template argument deduction happens before any implict conversions for
purposes of overload resolution, attempting to compare T with
std::reference_wrapper<T> simply looks like a comparison of unlike types.
For exapmle, std::reference_wrapper<std::string> is implicitly convertible to
'const std::string&', which would be able to choose an overload specialization
of operator==. However, the implicit conversion can only happen after template
argument deduction for operator==, so a specialization that would other be an
applicable overload is never considered.
Note also that this change only affects matchers. There are good reasons that
matchers may need to transparently hold a std::reference_wrapper. Other
comparisons (like EXPECT_EQ, et. al.) don't need to capture a reference: they
don't need to defer evaluation (as in googlemock), and they don't need to avoid
copies (as the call chain of matchers does).

Fix warning about deprecation of implicit operations such as copy constructors or assignment operators.
Specifically:
MatcherBase's default copy constructor, assignment operator, move operator, and move assignment operator are now declared explicitly rather than depending on the compiler implicit generation (which is disallowed/warned against due to MatcherBase's declaration of the destructor).
