Without this, compile warnings could be hit about __func__ being only
valid inside functions.

This allows specific tests to mock the check behavior to consistently
use exceptions instead of aborts for intentionally failing checks in all
build configurations.
When building with
BUILD_FOR_FUZZING=OFF
BUILD_FUZZ_BINARY=ON
CMAKE_BUILD_TYPE=Debug
allow the fuzz binary to execute given test cases (without actual
fuzzing) to make it easier to reproduce fuzz test failures in a more
normal debug build.
In Debug builds, deterministic fuzz behaviour is controlled via a runtime
variable, which is normally false, but set to true automatically in the
fuzz binary, unless the FUZZ_NONDETERMINISM environment variable is set.
