Switch on sealed types should offer autocomplete of types branches and not just the default branch

[nlisker]

Original issue here: https://bugs.eclipse.org/bugs/show_bug.cgi?id=576204. Still relevant in 4.31.

Concrete example:

sealed interface Type {

	final class A implements Type {}
	final class B implements Type {}

	default void a() {
		Type t;
		switch (t) {
		}
	}
}

A choice to get this result or thereabout should be offered:

switch (t) {
	case A a -> {}
	case B b -> {}
}

Note also that currently the default branch is added a switch statement (with default: break) rather than an expression (default -> {}), which users might not want as the default completion.

As this is a quickfix, not completion, and since quickfixes are implemented in jdt.ui, could you please file a separate ticket there? TIA

Transferred to eclipse-jdt/eclipse.jdt.ui#1459.

Is there any point in keeping this issue open, or does #1531 and the UI issue cover this?
