This CL migrates all the tests to TypeScript. The main benefits of this is that we start consuming our TypeScript definitions and therefore find errors in them. The act of migrating found some bugs in our definitions and now we can be sure to avoid them going forwards.
You'll notice the addition of some `TODO`s in the code; I didn't want this CL to get any bigger than it already is but I intend to follow those up once this lands. It's mostly figuring out how to extend the `expect` types with our `toBeGolden` helpers and some other slight confusions with types that the tests exposed.

The codebase was incredibly inconsistent with the use of spacing around
curly braces, e.g.:
```
// this?
const a = {b: 1}
// or?
const a = { b: 1 }
```
This extended into import statements also. Google's styleguide is no
spacing, so we're going with that.
This patch makes sure header overrides in request interception are
functioning as expected.
Drive-by: teach test server to use utf-8 charset header for text files.
This patch:
- implements Response.buffer() and other methods
- splits out relevant tests into a separate test suites
- implements `testServer.enableGzip()` method to optionally gzip
certain routes in tests
- adds tests to make sure `Response.text()` returns expected results
for binary and compressed responses.
