Adds support for "%v" in absl::StrFormat and related functions for string-like types (support for other builtin types will follow in future changes). Rather than specifying %s for strings, users may specify %v and have the format specifier deduced. Notably, %v does not work for `const char*` because we cannot be certain if %s or %p was intended (nor can we be certain if the `const char*` was properly null-terminated). If you have a `const char*` you know is null-terminated and would like to work with %v, please wrap it in a `string_view` before using it.

tests without requiring Abseil's tests be built (default=OFF)

This disables building libraries that are only used for writing tests
by default.

The logging library releases some libraries used for writing tests
that themselves depend on GoogleTest. This allows Abseil to build by
default without requiring GoogleTest.

Fixes #1262

It looks to me like the language rules treat these the same for this type, but evidently GCC feels differently.

This only matters under TSAN where SpinLock has a non-trivial destructor, and under C++20 where ABSL_CONST_INIT is implemented (as constinit) by gcc.

Before GCC 7.4, __cpp_lib_has_unique_object_representations was defined
but has_unique_object_representations_v was not.

When using Abseil as a dependency with CMake, files that include Abseil headers and have incompatible warning settings can emit compiler warnings. CMake allows you to mark include directories as `SYSTEM` includes, which causes compilers to ignore warnings from those headers. 

This adds the new option `ABSL_USE_SYSTEM_INCLUDES`, which makes Abseil's include directories be marked with `SYSTEM`.

The Lexan and MSVC toolchains both set _MSC_VER. The MSVC toolchain must set `ABSL_HAVE_STD_IS_TRIVIALLY_ASSIGNABLE` and `ABSL_HAVE_STD_IS_TRIVIALLY_CONSTRUCTIBLE`, in order to use Abseil workarounds in the absence of these types. This is not necessary for clang-cl.

This change excludes clang-cl from the predicate setting these variables.

There's no point redefining these functions if they are supported by the compiler and the version of libstdc++. Also, some of the builtins used by the absl implementation of these functions (e.g. __has_trivial_destructor) have been deprecated in Clang 15.
