[jdk19] RFR: 8289196: Patttern domination not working property for record patterns

[Jan Lahoda]

When checking that a pattern in a switch case is not dominated by a preceding pattern, handling for record pattern is mostly missing. This patch is attempting to fix that, and as it requires a bit more code, it moves the check into `Check`.
