* Migrate conditional tests to gate pragma
I searched through the codebase for this pattern:
```js
describe('test suite', () => {
if (!__EXPERIMENTAL__) { // or some other condition
test("empty test so Jest doesn't complain", () => {});
return;
}
// Unless we're in experimental mode, none of the tests in this block
// will run.
})
```
and converted them to the `@gate` pragma instead.
The reason this pattern isn't preferred is because you end up disabling
more tests than you need to.
* Add flag for www release channels
Using a heuristic where I check a flag that is known to only be enabled
in www. I left a TODO to instead set the release channel explicitly in
each test config.
