feat: add diff.maxDepth option and set non-Infinity value as a default to reduce crash

[hi-ogawa]

Description

• Closes Ability to customize how objects are printed in case of test failure #7478

I chose default 20 for mostly arbitrary reason. We want this as large as possible to be able to print diff that only happens in a deeper level, but the default should be a safer side from crash.
This default value is likely still too big for worst cases, but at least, OP's repro get smooth with this https://stackblitz.com/edit/vitest-dev-vitest-cewwclhz?file=test%2Fsuite.test.js.
