3bf67c175d Don't drop blocks on foreign functions
A code like

```rust
extern "C" {
    fn f() {
        fn g() {}
    }
}
```

is incorrect and does not compile. Today rustfmt formats this in a way
that is correct:

```rust
extern "C" {
    fn f();
}
```

But this loses information, and doesn't have to be done because we know
the content of the block if it is present. During development I don't
think rustfmt should drop the block in this context.

Closes #4313

46ab14437e Don't flatten a block containing a single macro call
We no longer flatten a block that looks like this:

```rust
match val {
    pat => { macro_call!() }
}
```

Currently, rust ignores trailing semicolons in macro expansion in
expression position (see https://github.com/rust-lang/rust/issues/33953)

If this is changed, flattening a block with a macro call may break the
user's code - the trailing semicolon will no longer parse if the macro
call occurs immediately on the right-hand side of the match arm
(e.g. `pat => macro_call!()`)

278e8da33b Add some basic tests for try{} expressions
They failed to parse in rustfmt on me in https://github.com/rust-lang/rust/pull/77877, which looks like it's since been fixed, but I figured I'd send in some tests anyway.

a15800a327 Preserve and format type aliases in extern blocks
Previously, non-trivial type aliases in extern blocks were dropped by
rustfmt because only the type alias name would be passed to a rewritter.
This commit fixes that by passing all type information (generics,
bounds, and assignments) to a type alias rewritter, and consolidates
`rewrite_type_alias` and `rewrite_associated_type` as one function.
