* [ts] Upgrade to TypeScript 3.9.2

This upgrades TypeScript to 3.9.2 to keep us more up to date. It also supports `@ts-expect-error` for places where we want to get notified if a future TS version stops triggering type checker errors. https://devblogs.microsoft.com/typescript/announcing-typescript-3-9/

It is also supposed to be faster but I don't have real numbers on this. CI might be a reasonable indicator.

Also updated ts-jest, since there was a bug that required clearing the Jest cache.

Updated the TS version in expo-module-scripts. Ran `expotools check-packages --no-uniformity-check ` to rebuild, test, and lint all files.
