Richard Smith 8f0f69b65f Remove RuntimeError / CompilationError. (#2258)
Instead, work out the prefix for an error based on whether it was produced during parsing, semantic analysis, or when running the program.

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
```

pk19604014 ed93d95fce Allow unknown fields in fuzzing text proto (#1296)
This is to help with frequent build breakages cased by proto changes.
Fuzzer corpus can be periodically auto-regenerated.
Crashing samples from the fuzzer are better 'preserved' in the form of fail_xx.carbon tests.

Jon Meow af694b97cb Prefix most macro names with CARBON_ (#1232)
I'm doing this to avoid macro name conflicts, following https://google.github.io/styleguide/cppguide.html#Preprocessor_Macros: "If you do export a macro from a header, it must have a globally unique name. To achieve this, it must be named with a prefix consisting of your project's namespace name (but upper case)."

Commands run:

```
sed -i 's/\(DCHECK\|CHECK\|FATAL\|MAKE_UNIQUE_NAME\|MAKE_UNIQUE_NAME_IMPL\|RAW_EXITING_STREAM\|RETURN_IF_ERROR\|RETURN_IF_ERROR_IMPL\|ASSIGN_OR_RETURN\|ASSIGN_OR_RETURN_IMPL\|DIAGNOSTIC_KIND\|RETURN_IF_STACK_LIMITED\)(/CARBON_\1(/g' $(git ls-files *.cpp *.h *.lpp *.ypp *.def ':!third_party')
sed -i 's/#undef DIAGNOSTIC_KIND/#undef CARBON_DIAGNOSTIC_KIND/' toolchain/diagnostics/diagnostic_registry.def
```

Note this isn't *quite* everything, but it's intended to be a large pass at everything:

```
╚╡git grep '#define ' *.cpp *.h *.lpp *.ypp *.def ':!third_party' | grep -v '#define CARBON' | grep -v _H_
explorer/syntax/lexer.lpp:  #define YY_USER_ACTION                                             \
explorer/syntax/lexer.lpp:  #define SIMPLE_TOKEN(name) \
explorer/syntax/lexer.lpp:  #define ARG_TOKEN(name, arg) \
explorer/syntax/parse_and_lex_context.h:#define YY_DECL                                                         \
migrate_cpp/cpp_refactoring/var_decl.cpp:#define ABSTRACT_TYPE(Class, Base)
migrate_cpp/cpp_refactoring/var_decl.cpp:#define TYPE(Class, Base)     \
```

We may in particular want to do a pass to clean up #ifdef guards and make them be CARBON_ rooted.

pk19604014 150057f260 Added GetRunfilesFile() to be able to reliably determine prelude location under various invocation scenarios
The logic is using bazel Runfiles API per Jon's suggestion.

One of the scenarios used by the fuzzing framework is to place the binary and its runfiles into a folder, resulting in a directory layout like this:

[temp dir]
fuzzer
fuzzer.runfiles/

Tested:
bazel test -c opt explorer/fuzzing:explorer_fuzzer
bazel build -c opt explorer/fuzzing:explorer_fuzzer + run the binary from various locations
