feat(jest-runner): support mutation switching (#2350)

Add mutation switching support (new test runner API) for `@stryker-mutator/jest-runner`.

* Implement new test runner interface in `@stryker-mutator/jest-runner`.
* Add `sandboxFileName` to `RunOptions` and use that in the jest runner to provide the "fileNameUnderTest"
* Enable 3 jest e2e tests
* Add support for `.tsx` files to `@stryker-mutator/instrumenter`
