  [clang] Implement setting crash_diagnostics_dir through env variable

This implements setting the equivalent of `-fcrash-diagnostics-dir`
through the environment variable `CLANG_CRASH_DIAGNOSTICS_DIR`.
If present, the flag still takes precedence.

This helps integration with test frameworks and pipelines.

With this feature, we change the libcxx bootstrapping build
pipeline to produce clang crash reproducers as artifacts.
