Enable project filtering on vitest workspace scenarios

[TheMineWay]

Clear and concise description of the problem

When working with Vitest UI on a monorepo it could be useful to be able to filter tests by project. This can make it easier to navigate through big projects with multiple tests.

Suggested solution

Add, for example a dropdown, where you can choose which projects you want to show. When filled, the tests list will only show tests assigned to selected projects.
