It looks like this pull request may not have tests. Please make sure to add tests or get an explicit test exemption before merging. If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix? Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. If you believe this PR qualifies for a test exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group. |

Code Review
This pull request introduces a Dart wrapper for the zx_iob_writev Zircon syscall. This involves adding an external function in Dart, its corresponding C++ implementation in the zircon::dart::System class, and registering the native binding. The changes are consistent with existing syscall wrappers in the project. My review includes two comments suggesting the addition of documentation for the new public APIs in both Dart and C++, as required by the repository's style guide.

Unfortunately, I don't think there's an easy way to add a test for this because it's possible to create IOBuffers from dart. I need to add this because Fuchsia logging now uses IOBuffers rather than sockets, so some logging code that I have will need this. ## Pre-launch Checklist - [X] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [X] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [X] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [X] I signed the [CLA]. - [X] I listed at least one issue that this PR fixes in the description above. - [X] I updated/added relevant documentation (doc comments with `///`). - [X] I added new tests to check the change I am making, or this PR is [test-exempt]. - [X] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [X] All existing and new tests are passing.
