Switch to a testing framework that is not Jest

Some options:

1. "Oxidize" the Jest — no changes to the tests
2. Vitest — some changes to the tests
3. Built-in Node.js test runner (since v18) — even more changes to the tests, plus some additional setup of tsx OR using experimental type stripping of Node.js, or its experimental type transformations: node --experimental-transform-types. All to continue writing tests with TypeScript

For all but the first option, one would probably have to rewrite the @ton/test-utils, since they only provide methods for Chai and Jest.
