feature(expect): Return the error from toThrow and toThrowError

[chrisblossom]

Summary

When working with a project that uses ava I noticed their .throws and .throwsAsync return the original error. It is very convenient.

This would make it possible to never need the expect.hasAssertions() + try / catch syntax.

Closes #8698.

Test plan

Added several tests.

[chrisblossom]

I am unsure why the "lint-and-typecheck" run is failing. I am unable to reproduce locally.

rm packages/*/tsconfig.tsbuildinfo && yarn watch:ts passes locally?

[chrisblossom]

No it doesn't. Not sure what I was doing before. Going to hold off on fixing the errors until the discussion in #8698 is resolved.
