This is to add build fingerprint and product name/version to microdumps. Conversely to what happens in the case of minidumps with MIME fields, due to the nature of minidumps, extra metadata cannot be reliably injected after the dump is completed. This CL adds the plumbing to inject two optional fields plus the corresponding tests.
