FUZZ_TEST_F Should Respect GTEST_SKIP() in GoogleTest Base Fixture

GoogleTest allows calling GTEST_SKIP() in the SetUp() method of a fixture to skip all tests that use that fixture: https://google.github.io/googletest/advanced.html#skipping-test-execution.

FUZZ_TEST_F on the other hand continues to run the test. The test output is also confusing in this scenario. The logs and command line output indicate the test failed, but the status of each test appears to be skipped.

Minimal Example:
```cpp
#include "testing/base/public/gunit.h"
#include "testing/fuzzing/fuzztest.h"
#include "third_party/googlefuzztest/googletest_fixture_adapter.h"

namespace {

class SkipFixture : public testing::Test {
protected:
void SetUp() override { GTEST_SKIP(); }
};

class FuzzTestFixture
: public ::fuzztest::PerFuzzTestFixtureAdapter {
public:
void FailingTest() { FAIL(); /*Not Skipped*/ }

void FailingTestIsSkipped() {
GTEST_SKIP();
FAIL(); /*Skipped*/
}
};

TEST_F(SkipFixture, FailingTestIsSkipped) { FAIL(); /*Skipped*/ }

FUZZ_TEST_F(FuzzTestFixture, FailingTest); // Test Fails!
FUZZ_TEST_F(FuzzTestFixture, FailingTestIsSkipped);

} // namespace
```
