Our in-tree copy of webrender/Cargo.toml has this [profile.release] section [1] that isn't in the upstream webrender. We added this when we were building webrender manually with |cargo build| to get better debugging. However now that the in-tree WR is built as part of gkrust, this section is ignored (as per Cargo docs [2]). And the root gkrust Cargo.toml already has those particular lines [3]. To reduce the diff to upstream WR we can drop these lines from our in-tree WR.
