+Subject: Merge M110: "Improve checks for VideoFrame layouts."
+
+Adds a `VideoFrameLayout::IsValidForSize(size)` method which clients can
+use to verify a VideoFrameLayout for their purpose. Updates a few call
+sites to use the new verifier and adds tests.
+
+(cherry picked from commit 17f73200c066158330542c19d521c517586533a2)
