Support running jasmine multiple times

Add support for running jasmine multiple times.

```js
const Jasmine = require('jasmine');

async function main() {
  const jasmine = new Jasmine({ projectBaseDir: process.cwd() });
  let specId = 'spec0';
  jasmine.loadConfigFile('./spec/support/jasmine.json');
  jasmine.env.configure({
    specFilter(sp) {
      return sp.id === specId;
    },
    autoCleanClosures: false
  });
  jasmine.exit = () => {};
  await jasmine.execute();
  specId = 'spec2';
  await jasmine.execute();
}

main().catch((err) => {
  console.error(err);
  process.exitCode = 1;
});
```

With `jasmine.env.configure({ autoCleanClosures: false })` you disable Jasmine's feature to automatically clean closures (functions) during the test run. This is a requirement to be able to rerun.

When `execute` is called more than once, the `topSuite.reset` is called, which will reset the state for the next run as well as reset any child suites.

Add a function `exclude` to the `Suite` and `Spec` clases. This functions similar to `pend`, but will allow the "pending" state to persist over multiple runs. This is useful when `xit` is used.

Revert changes to jasmine.js

fix: make sure to call hooks during second run

Remove jsdoc from private apis
