Jordan Whited df6014f1d7 net/tstun,wgengine{/netstack/gro}: refactor and re-enable gVisor GRO for Linux (#13172) ... In 2f27319baf we disabled GRO due to a data race around concurrent calls to tstun.Wrapper.Write(). This commit refactors GRO to be thread-safe, and re-enables it on Linux. This refactor now carries a GRO type across tstun and netstack APIs with a lifetime that is scoped to a single tstun.Wrapper.Write() call. In 25f0a3fc8f we used build tags to prevent importation of gVisor's GRO package on iOS as at the time we believed it was contributing to additional memory usage on that platform. It wasn't, so this commit simplifies and removes those build tags.
