Feature Request: Create spyReset to only reset spies, not other mocks

[NateRadebaugh]

Clear and concise description of the problem

With the new 3.0 release, "vi.spyOn Reuses Mock if Method is Already Mocked" is a breaking change without a simple migration strategy.

https://vitest.dev/guide/migration.html#vi-spyon-reuses-mock-if-method-is-already-mocked

While we can configure "mockReset" in the vitest config, or explicitly call "mockRest" in the "beforeEach", this also blows away other mocks that may have been configured.

It would be great if we could have a new spyReset to only reset spies. Right now we have a number of tests verifying a spy was called N times, and explicitly cleaning up each spy manually using onTestFinished callback is klunky at best.

Suggested solution

Create new spyReset that can be configured in vitest config, or called manually, to only reset spyOn spies instead of all mocks.
