Add fuzzing test on function resolv_getaddrinfo for DnsResolver.

Bug: 240913174

Test: sees go/android-fuzzing-run or uses commands below

 # Build & run
FUZZER_NAME=resolv_getaddrinfo_fuzzer
DEVICE_TRACE_PATH=/data/fuzz/$(get_build_var TARGET_ARCH)/${FUZZER_NAME}/data.profraw
CLANG_COVERAGE=true NATIVE_COVERAGE_PATHS='*' make ${FUZZER_NAME}
adb sync data && adb shell LLVM_PROFILE_FILE=${DEVICE_TRACE_PATH} /data/fuzz/$(get_build_var TARGET_ARCH)/${FUZZER_NAME}/${FUZZER_NAME} -runs=10000

 # Check results
adb pull ${DEVICE_TRACE_PATH} data.profraw
llvm-profdata merge --sparse data.profraw --output data.profdata
llvm-cov show --format=html --instr-profile=data.profdata ${ANDROID_PRODUCT_OUT}/symbols/data/fuzz/$(get_build_var TARGET_ARCH)/${FUZZER_NAME}/${FUZZER_NAME} --ignore-filename-regex='\/frameworks\/' --ignore-filename-regex='\/rust\/crates\/' --ignore-filename-regex='\/system\/' --ignore-filename-regex='\/external\/' --ignore-filename-regex='\/\.intermediates\/' --output-dir=coverage-html
