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.

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.

Abseil failed to configure with `ABSL_PROPAGATE_CXX_STD` if the compiler was not known to CMake:
target_compile_features no known features for CXX compiler
Turns the error into a warning by checking `CMAKE_CXX_COMPILE_FEATURES`
before calling `target_compile_features`.

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.

In the case that we are unwinding with context, if the retreived frame pointer
matches the signal context, assume that the value is valid and do not perform
confidence checks. In any other case, continue to perform some validation to
avoid returning an incorrect frame pointer.
Given that the VDSO path is currently untested, remove the code to simplify the
logic in the frame walking.

The changes in d6f96eda14 enabled handling cases
where the stack may be non-contiguous or not fully symbolicated (e.g. in cases
of alternate signal stacks). However, it did not properly honour the requests
from the caller to perform a strict unwinding where such frames are terminated
upon the discontinuity. This repairs that condition.
Hoist the alignment check since that is safe to perform early.
