Fix invalid print output when empty array is passed to t.tsInterfaceDeclaration (#12921)
If you pass an empty array as `extends` in `t.tsInterfaceDeclaration` you'll get an invalid code printed

```ts
t.tsInterfaceDeclaration(
  t.identifier('x'),
  undefined,
  [],
  t.tsInterfaceBody([])
)
```

You will get
```ts
interface A extends {}
```

Which is an invalid TS, this PR fixes that

Allow nullish extends in interfaceish (#12920)
* Allow nullish extends in interfaceish

Otherwise code such as

```ts
t.interfaceDeclaration(
  t.identifier('id'),
  undefined,
  undefined,
  t.objectTypeAnnotation([])
)
```

Will fail when priting with ` TypeError: unknown: Cannot read property 'length' of null`
Despite nullish values being allowed in `t.interfaceDeclaration` definitions

* Update packages/babel-generator/src/generators/flow.ts

This is a mix of changes, most importantly:

- Always print parens when mixing nullish coalescing and another logical
- Fixes assignment in the callee of an optional chain, which now blocks #11248

Also, cleans up a bit of code, and removes an unnecessary parens around `class A extends new B {}`
