[snap tester] Support @only / @skip with special file

--- 

Changes: 

- Added `testfilter.txt` 

``` 

// @only 

call 

capture-param-mutate 

jsx-spread 

``` 

or 

``` 

// @skip 

call 

error.todo-kitchensink 

``` 

- grouped all commands under `--mode` 

```js 

// runs all tests 

yarn snap 

// runs all tests and updates fixtures 

yarn snap --mode update 

// runs only tests that pass `testfilter.txt` 

yarn snap --mode filter 

// run in watch mode 

yarn snap --mode watch 

``` 

- in watch mode, toggle between running all tests or filtered tests 

```

- `runner.ts` is pretty large now, happy to split it up into multiple files 

- I'd also like to refactor `watch` to make its shared state and control flow 
explicit
