[zanderso]

This is a CP PR for

• Use traingle strip for difference clip #37469, and
• [Impeller] Include the new primitive type in the pipeline hash #37546

Which fix flaky rendering issues in Impeller.

We might want to also throw #37561 into the mix. I think the reason we haven't noticed it yet is that the default CTM is nearly always scaled up a bit on high DPI devices. For example, on my iPhone 12 Mini, the CTM gets scaled up by 3x on all of the DisplayLists that Impeller receives -- that leaves a buffer on the bottom and right sides of the layer and masks the problem for some appended scales and translations in the -x/-y direction.

@zanderso did we want to add #37561 as referenced by @bdero?

If that one is needed, I'll file a separate issue and PR for it. So it doesn't need to be included in this one.

@godofredoc there seems to be an error in .ci.yaml from a change in 0075e10. Do you know how to resolve this so we can get this cherry pick in for the next beta?
