It looks like this is very nearly ready in upstream Chromium, apparently just blocked on [this CL](https://chromium-review.googlesource.com/c/crashpad/crashpad/+/2037803), which has to do with an upload issue on Fedora.

Upstream tracking issue: https://bugs.chromium.org/p/crashpad/issues/detail?id=30

Once this CL is landed we should consider enabling Crashpad on Linux and removing our Breakpad-related code.
