fix(parser): parse empty method declaration as TSEmptyBodyFunctionExpression (#2574) 
That a tricky one, because it's time to decide what does ESTree
compliant means in the TS world (re #2463)

This code:

```ts
export declare class ByteBuffer {
  clear(): void;
     // ^^
}
```

- Is parsed by
[Babel](d38530204e)
as `FunctionExpression` with an empty body
- By
[TS-ESLint](4ea4e2feb5)
as
[TSEmptyBodyFunctionExpression](https://github.com/typescript-eslint/typescript-eslint/pull/1289)
- By
[OXC](https://oxc-project.github.io/oxc/playground/?code=3YCAAIC1gICAgICAgICyHorESipoTXPdvBaE9wxzlOraoWs19SUxDvdcwSVU0kbBO2b7ppX3x2P5IhQlpGHOYEHNCEfLf38HUICA)
as `TSDeclareFunction`

I'm going the easy way to fix this to the Babel way, but I think
following TS-ESLint would make sense. There is an [open babel
issue](https://github.com/babel/babel/issues/13878) about that.

Edit: Ok that not so easy and require updating some logic.

Coverage

The parser is tested against test262, babel and TypeScript for conformance.

Note: tests against regexp are disabled for now.

Clone the test files beforehand:

git submodule update --init

Development

# full run
cargo coverage
cargo coverage js # for test262
cargo coverage babel # for babel
cargo coverage ts # for typescript

# run in watch
cargo watch -x 'coverage js'

# filter for a file path
cargo watch -x 'coverage js --filter filter-file-path'
