This adds debugging support to jest-runner for the integration tests
when they are run from the `out` directory. Unfortunately, this removes
the ability to debug the non-integration tests, such as the pure tests.
This converts all pure tests to Jest. This was done by first running
`npx jest-codemods` with the Mocha transformation, then manually fixing
any places where it hadn't automatically converted the correct thing
or had missed things (mostly Sinon).
This also sets up VSCode correctly for running Jest.
This adds Prettier and makes it replace tsfmt. VSCode is set to use
Prettier for formatting TypeScript/TSX files and format on save since
Prettier is very fast and does not cause any noticeable delay.
