lgtm, we have test coverage in the golden tests. Technically we are losing test coverage in the non msaa case. That's mostly a subset of the msaa code though so it's not the end of the world. (I'm saying that specifically to incriminate us if it ever does become a problem in the future haha)

I think the comment above needs to be updated.

nit: I think sending in the Capabilities would be a better interface. It's more clear where people are getting this for and what the purpose is.

Add support for MSAA without the render to texture extension. This allows our CI goldens to run with anti aliasing. Fixes flutter#158360 (again)
