Add support to not add newlines in switch expressions

### Description

As a software engineer I would like to allow switch expressions to format the same as switch statements so that I can better align my code.

Currently if I were to try to format the following statement:

```java
return switch (av.type()) {
case B -> av.b().asByteArray();
case BOOL -> av.bool();
case BS -> av.bs().stream()
.map(SdkBytes::asByteArray)
.collect(toList());
default -> null;
}
```

It will be formatted as:

```java
return switch (av.type()) {
case B ->
av.b().asByteArray();
case BOOL ->
av.bool();
case BS ->
av.bs().stream()
.map(SdkBytes::asByteArray)
.collect(toList());
default -> null;
}
```

This makes the statement decidedly less readable and does not align with my switch statement settings.

### Use case/motivation

Allow for better readability and consistency with switch statements.

Yes

Start by locating the Java formatter entry point that handles switch expressions and compare it with switch statement formatting. Use the examples in the issue to verify that single-line arrow cases remain on one line, and add or update formatter coverage so the shown output is preserved.
