aro_translate_c: do not translate _Static_assert declarations

This does not completely ignore static asserts - they are validated by aro during parsing; any failures will render an error and non-zero exit code. Emit a warning comment that _Static_asserts are not translated - this matches the behavior of the existing clang-based translate-c. Aro currently does not store source locations for _Static_assert declarations so I've hard-coded token index 0 for now.
