cleanup: split CMakeLists.txt and add some missing targets

# Override network and random functions
refactor: Avoid `static_cast` in `Fuzz_System` functions. Declutters the fuzz system code a bit, hiding the cast behind a `!` operator.

set(LIBFUZZER_LINKER_FLAGS)
test: Add fuzz tests to the coverage run. So we don't need to write so many edge case tests ourselves for things like parsers, which really don't need those manual tests, as long as we can check for some properties like "can output the parsed data and it'll be the same as the input".

function(fuzz_test target source_dir)
fix: Make all the fuzzers work again, and add a test for protodump. fuzz_select_target wasn't selecting anything, so fuzzers using that function either did nothing or would only ever select one of the functions.

add_executable(${target}_fuzz_test ${source_dir}/${target}_fuzz_test.cc)
test: Add C++ classes wrapping system interfaces. These are more convenient and safer than the manual vtables we have in the fuzzer support code. We can override individual member functions, and C++ will take care of correctly casting and offsetting this-pointers when needed.
