Jordan Whited	7675c3ebf2	wgengine/netstack/gro: exclude importation of gVisor GRO pkg on iOS (#13202) ... In df6014f1d7 we removed build tag gating preventing importation, which tripped a NetworkExtension limit test in corp. This was a reversal of 25f0a3fc8f which actually made the situation worse, hence the simplification. This commit goes back to the strategy in 25f0a3fc8f, and gets us back under the limit in my local testing. Admittedly, we don't fully understand the effects of importing or excluding importation of this package, and have seen mixed results, but this commit allows us to move forward again.

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.
