Add a new
libfuzzer_dotnet_fuzztask to the agent.This task has a config which is an extension to the
libfuzzer_fuzzwith 3 extra parameters:target_assembly,target_class, andtarget_method. At runtime, it uses the newLibFuzzerType::extra_setup()hook to to instrument thetarget_assemblyfor coverage feedback using SharpFuzz, and generateslibfuzzer-dotnet-based fuzzer invocations ofLibFuzzer. These useLibFuzzerDotnetLoaderas the--target_patharg forlibfuzzer-dotnet, and sets the env vars that tellLibFuzzerDotnetLoaderwhat to fuzz.
