Fix error handling in skyframe target pattern parsing

Bazel completely swallowed errors in some cases, e.g., if the pattern is
invalid like bazel build foo//bar:baz.

Note that it previously silently ignored empty targets if --experimental_skyframe_target_pattern_evaluator was passed, and now fails (which is consistent with legacy behavior). This is an intentional change, but may break users who are using the experimental flag and are passing empty strings to Bazel.
