[Bug]: Compilation fails with Clang15

[abhinandanudupa]

Describe the issue

Using the clang 15 compiler gives the error:

...gtest-src/googletest/include\gtest/internal/gtest-internal.h(918,54): error: out-of-line definition of constexpr static data member is redundant in C++17 and is deprecated [-Werror,-Wdeprecated]
constexpr bool HasDebugStringAndShortDebugString<T>::value;
                                                     ^
1 error generated.

Redundant declarations have been deprecated in C++17.
