Add `vi.createMockFromModule` (Like `jest.createMockFromModule`)

Clear and concise description of the problem

I want to create a manual mock (__mocks__), but only specialize parts of the default mock that is automatically created by vitest, in Jest I could do:

import { jest } from '@jest/globals';

const mod = jest.createMockFromModule<typeof import('../foo')>('../foo');
mod.bar = jest.fn(() => 'qux');
export = mod;

But createMockFromModule is not available in Vitest, and importMock is not the same, as when used inside a manual mock, it just ends up importing the manual mock itself cyclicly. createMockFromModule always returns the automatically created mock object even if there is a manual mock.

Suggested solution

Add vi.createMockFromModule or under a different name that better fits it's async nature in vitest, that acts like vi.importMock but always return an automatically created mock even if there is a manual mock.

Alternative

Manually mock everything in the manual mock, which is cumbersome and harder to maintain.

Additional context

Encountered while migrating some tests from Jest to Vitest due to Jest's ESM issues.

• Follow our Code of Conduct
• Read the Contributing Guidelines.
• Read the docs.
• Check that there isn't already an issue that request the same feature to avoid creating a duplicate.

Start by reading the existing vi.importMock behavior and the manual-mock flow described in this issue, including how mocks is resolved. Define the new API's async behavior and verify that it returns the automatically generated mock rather than the manual mock, including the partial-specialization use case shown above.
