Jon Ross-Perkins b1ee45c1e4 Extract ParseAndExecute as its own library. (#2813) 
Currently ParseAndExecute-style logic is done in main.cpp and a test. #2799 is adding another test that needs it, as is #2811.

Also more clearly marks fuzzing as testing.

This is being extracted out of #2799 in order to try unblocking progress while review continues.

Jon Ross-Perkins d12583fc08 Do cleanup on explorer fuzzing infrastructure. (#2790) 
I'm partly doing this because the current setup would be difficult to share with the toolchain. e.g., ProtoToCarbon isn't explorer-specific, but the only way to run it via CLI is the explorer's fuzzverter. I want a separate tool.

This change:

- Adds a //common/fuzzing:proto_to_carbon tool.
  - The rest of fuzzverter is now just //explorer/fuzzing:ast_to_proto.
  - The change simplifies overall handling and removes a LLVM CLI dependency.
- Stops allowing unknown fields in the proto.
  - This has mostly led to forgetting to remove fuzzer inputs that were for removed features.
- Moves more non-explorer-specific bits to //common/fuzzing.
- Cleans up remaining pieces in //explorer/fuzzing
  - Merges the //explorer/fuzzing proto tests, which deduplicates AstToString copies.
    - These tests also had duplicate dependencies, etc -- and all complete in ~6s.
  - Updates and fixes regen_corpus which was previously broken by other changes.
  - Updates the README to reflect changes.
- Removes obsolete proto-fuzzer build configuration (AFAICT this is no longer needed).

Jon Ross-Perkins b07f9295d7 Stop printing per-input results in fuzzer (#2780) 
Right now, running the fuzzer in fuzzing mode is pretty noisy due to this output; it makes it hard to see the fuzzer's own progress output. It's also not really needed: users can run explorer on inputs more directly, without using this tool (albeit with fuzzverter), if they want to see detailed results.

Jon Ross-Perkins 4d522c8e90 Finish making clang-tidy (mostly) work (again) and run -fix (#2312) 
This does some more work to the run_clang_tidy.py wrapper script, and runs an example pass.

"again" because it's really the proto fuzzer changes that broke it, it had been working before.

"mostly" because there's still an issue within the proto fuzzer that it can't find "port/protobuf.h", i.e. https://github.com/google/libprotobuf-mutator/tree/master/port, but I'm still hesitant to add an include path there.

pk19604014 98d95cd188 Cleanup: since explorer_fuzzer is now a standard cc_fuzz_test, and runs on all files in the corpus, there's no need for fuzzer_util_test to do the same manually 
Before:
```
//explorer/fuzzing:fuzzer_util_test                                      PASSED in 18.5s
```

After:
```
//explorer/fuzzing:fuzzer_util_test                                      PASSED in 0.3s
```
